Investigation of the gap vortex street in densely packed tube arrays in axial flow using CFD and experiments
No full textAxial flow in tube bundles with small pitch-to-diameter ratio, a geometry encountered in nuclear reactor cores and heat exchangers, often displays periodic fluctuations. A significant velocity discrepancy between the inter-cylinder gap and subchannel center originates from the difference in through-flow area, feeding an instability. As it is associated with velocity-shear, it is similar to the Kelvin-Helmholtz type and the term 'gap instability' is adopted. A vortex street arises and structural vibration of the cylinders might develop due to the fluctuating pressure. Numerical simulations of this phenomenon were performed. The computational domain was constructed to match the most important geometrical features of an experimental setup. The bundle consists of 7 steel tubes in triangular array, placed in a hexagonal conduit. A flexible segment made of silicone is embedded in the central tube, with both extremes clamped to the steel parts of the cylinder. In the experiment, data of the fluctuating velocity was gathered using laser Doppler anemometry measurements. As first step, a completely rigid structure was considered. Unsteady Reynolds-averaged Navier-Stokes (URANS) simulations were used to test if this particular geometry also triggers the gap vortex street, which was the case. The phenomenon clearly appears as oscillations of the velocity components. Subsequently, fluid-structure interaction (FSI) simulations, taking into account the flexible part, allowed to assess the effect of the fluctuating flow field on the structure. A comparison between one-way and two-way coupled simulations was made.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.RST/Reactor Physics and Nuclear Material
Polyphony and the anxiety of influence in the fiction of Henry James
Full text linkJames's fiction, especially in the Middle Phase, centres
on the figure of the artist and is characterized by, the two
interrelated aspects which previous criticism has largely
overlooked: the Bakhtinian 'polyphonic' -creation of
'author-thinkers'; and the conflict between ephebes and
precursors, for which Harold-Bloom's concept of 'the-anxiety of
influence' is the most illuminating model. Polyphony is the
narrative mode, and influence is the intra-artistic, theme.
These, as the Introduction to the thesis makes clear, are
rehearsed in James's inaugural novel, Roderick Hudson. Rowland
Mallet is an author-thinker, and his failure is caused by
authorial limitations. His monologism -is impaired by his
mistaking empathy for the authorial sympathy. Likewise,
Hudson's failure does not arise from a mercurial temperament,
but from a polyphonic shortcoming: not possessing the power of
fiction to contain the fiction of power in, his mentor. And the
relationships among the three artists - Gloriani, Hudson and
Singleton - perfectly exemplify the Bloomian-theme. It is these
two concepts, polyphony and influence, which are the major
preoccupation in the Middle Phase; as, the works chosen
demonstrate. These are a novella, a novel, and a number of
short stories all of which have been unjustifiably neglected.
Chapter One, on The Aspern Papers, argues that Tina Bordereau,
far from being, the artless victim seen by many critics,
actually challenges and defeats the narrator by the very form
of her narrative. Her 'realist' discourse undermines his
language of 'romance', and shows up its internal unstability.
Chapter Two is an extensive study of the critical reception of
The Tragic Muse. The most common areas of critical attention
have been its contemporary topicality, its relation to previous
novels on similar themes, and the possible genealogy of Gabriel
Nash. Those have all missed the core of the work. - Chapter Three
demonstrates how polyphony and the anxiety of influence make
the novel what it really is. Influence arises from the
juxtaposition of, and the wrestling between, artistic ephebes
and their precursors (Nick and Nash,, Miriam and Madame Carre).
The dialogic quality defined by Bakhtin is crucial to the
proper, and even-handed, characterization of all, the conflicts
in the novel. And since most of James's tales in the eighties
and nineties -are about 'masters - and acolytes, the anxiety of
influence remains central. Chapter Four is a study of 'The
Author of Beltraffiol' and 'The Lesson of the Master'. Again the
characters' manipulations are a crucial focus in a way that
G6rard Genette's terminology helps to illuminate. The fact that
the ephebe is the author-thinker emphasizes the inextricability
of the Bakhtinian and the Bloomian in James. Just as
polyphony offers a different focus for explicating the poetics
of James's fiction; so the ephebal conflict provides the basis
for a fresh perception of James's own artistic struggle
The Center for Ray Bradbury Studies: A Case Study in Sustaining a Single Author Archive
No full textIndiana University-Purdue University Indianapolis (IUPUI)The Center for Ray Bradbury Studies (cited also as the “Bradbury Center” or the “Center”) is a single author archive, museum, and outreach center housed in the Institute for American Thought, located in the School of Liberal Arts at IUPUI. This dissertation employs a case study methodology to explore the complex issue of single author archive management and sustainability as it applies to the Bradbury Center by extending the research process beyond working with primary sources and published materials.
The applied research project unfolded in two phases. The first involved an intensive four-day on-site consultation in which five professional archivists and preservation experts from across the Midwest visited the Bradbury Center and examined its collections and policies. Following their visit, the consultants prepared recommendations concerning artifacts, manuscripts, correspondence, physical layout, access, operational procedures, processing priorities, and environmental/climate control for artifacts. The on-site consultation team also informed objectives, goals, and strategies for addressing the preservation needs of the Center’s vast and varied collections, aiding in systematically moving forward with curatorial initiatives, and planning for general organizational development.
The second research phase involved site visits to five peer institutions to tour facilities, interview directors and archivists about best practices, and established a plan for adapting these practices to the Bradbury Center. Findings from both research phases inform the Bradbury Center’s immediate and long-term plans for center staff, fundraising, spatial expansion and renovation, and the Center’s strategy for identifying key constituencies as it endeavors to serve a broad spectrum of public and academic audiences through various outreach and programming initiatives.
Upon completion of the case study field research, a formal report was prepared. That report serves as the cornerstone for this applied dissertation. Additional chapters cast a vision for the Bradbury Center and address potential opportunities to serve the Indianapolis region by tapping into tourism markets, conventions, and local cultural festivals and celebrations while also developing into an international research hub as the sole entity that preserves the material legacy of Ray Bradbury. The introductory chapter situates the Bradbury Center within the legacy of the central figure of the Center—Ray Bradbury
Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state
Case Study of Condensate Dropout Effect in Unconventional Gas/Condensate Reservoirs with Hydraulically Fractured Wells
No full textCondensate banking is a major issue in the production operations of gas condensate reservoirs. Increase in liquid saturation in the near-wellbore zone due to pressure decline below dew point, decreases well deliverability and the produced condensate-gas ratio (CGR). This paper investigates the effects of condensate banking on the deliverability of hydraulically fractured wells producing from ultralow permeability (0.001 to 0.1 mD) gas condensate reservoirs. Cases where condensate dropout occurs over a large volume of the reservoir, not only near the fracture face, were examined by a detailed numerical reservoir simulation. A commercial compositional simulator with local grid refinement (LGR) around the fracture was used to quantify condensate dropout as a result of reservoir pressure decline and its impact on well productivity index (PI). The effects of gas production rate and reservoir permeability were investigated. Numerical simulation results showed a significant change in fluid compositions and relative permeability to gas over a large reservoir volume due to pressure decline during reservoir depletion. Results further illustrated the complications in understanding the PI evolution of hydraulically fractured wells in "unconventional" gas condensate reservoirs and illustrate how to correctly evaluate fracture performance in such a situation. The findings of our study and novel approach help to more accurately predict post-fracture performance. They provide a better understanding of the hydrocarbon phase change not only near the wellbore and fracture, but also deep in the reservoir, which is critical in unconventional gas condensate reservoirs. The optimization of both fracture spacing in horizontal wells and well spacing for vertical well developments can be achieved by improving the ability of production engineers to generate more realistic predictions of gas and condensate production over time.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Civil Engineering & GeosciencesReservoir Engineerin

The queen and the laureate: social media poets and the creation of minor literatures
No full textThis thesis works to answer the question: how does social media work to democratize poetry? What is the limitation of social and digital media to create a space where any poet can succeed? The work uses Deleuze and Guattari’s theory of minor literatures to frame the work of social media poets. Using a case study analysis, focused on two poets in particular, the work illuminates the effects of social media on how they create art. This thesis will examines the larger cultural implication of fringe art as is incorporated into dominant literature discourses and resists appropriation
Canine immune-mediated polyarthritis: clinical and laboratory findings in 83 cases in western Canada (1991-2001).
No full textA hospital-based, case-control study was used to describe clinical and laboratory findings in 83 dogs diagnosed with noninfectious, nonerosive, immune-mediated polyarthritis (IMPA) in western Canada. Case medical records were reviewed. Cases were analyzed as total IMPA cases and as subgroups [breed, systemic lupus erythematosus (SLE), reactive, and idiopathic] and compared with the general canine hospital population. Dogs with IMPA differed in age (P = 0.004) and weight (P = 0.01) from other hospital admissions. Idiopathic IMPA cases were older (4-10 y; P < 0.05), compared with the general canine hospital population, and their common laboratory abnormalities included the following: leukocytosis, nonregenerative anemia, increased alkaline phosphatase, and hypoalbuminemia. The SLE cases were seen more often in summer and fall (P = 0.04), raising concern of an undiagnosed etiologic agent. The hock joint appeared to be the most reliable for diagnosis of IMPA, and arthrocentesis of both hock joints may aid in case identification.journal article2008 Decimporte
