A New Method to Determine Heat Loads in Thermal Storage and Fluid Transport Tthrough Underground: Degree-hours
No full textEstimating the heat load of any thermal system is extremely important in thermal storage and fluid transport applications. Heat load estimates are related to temporal temperature changes. In this study, a novel degree-hour method, which takes into account the fluid temperature and soil temperature, is proposed to determine the heat loads of underground fluid storage and transportation systems. Thus, heating and cooling degree-hours are calculated for two cities with cold and hot climates as Izmir and Erzurum in Turkey. In addition, the temperatures of the stored and transported fluid are selected between -40 and +40 °C in intervals of 10 °C. Finally, theoretical implications for degree-hour calculations are presented in general terms, and a simple application is given for two cities in Turkey. The good performance of the degree-hour method is documented by the figures

No full textTo assist the policy makers for effectively managing the diffusion process of the EVs technology in Oman, it is important to build a comprehensive understanding of the mechanisms behind the diffusion process of such technology. This study endeavors to provide the policy maker with a tool to accelerate the diffusion of EVs in Oman. The AHP model was used to identify the dominant criteria that influence the diffusion of EVs in Oman. Three important criteria were evaluated i) Infrastructure, ii) Zone activity and iii) Social parameter. AHP is widely used as a decision-making tool using pair-wise comparisons concept of different alternatives with respective to various criteria. The flexibility of charging in term of distance between fuel stations of different zones were measured and evaluated. It was found that the zone active density as well as the traveling distance between locations (Zones) are key parameters that should considered for identifying the best location for charging stations to. Having a clear picture of zone activity in Oman is an essential parameter to assist the decision-maker to make an efficient plan and develop the construction of the existing infrastructure to accelerate EVs technology
Radiator selection by considering building heat loss calculations according to ts-825 standard
No full textPanel radiators are finned natural convective heat exchangers. Water flows inside chanels and outside air is heated up through finned and bare surfaces of heat exchanger. Radiator thermal performance measurements are carried out in companies labs according to EN 442-2 standard for testing radiators and convectors. Results are curve fitted according to EN 442-2 for various sizes. In order to select optimised panel radiator for domestic space heating, room heat loss should be determined accurately. Turkish standard TS-825 is given detailed definitions to determine heat loss of a building and a room. A computer model is designed according to description and data given in this standart to determine the heat loss of a single room. In heat loss considiration of the single room, each wall, ceiling etc. is investigated by also considering neigbour spaces, i.e if it is and outside or internal space, direction of the wall, location and outside conditions according to locations etc. As a part of the walls window and door heat transfers, air leaks, room air refrefshments requirements are alos considered. All this calculations are offered to user in friendly graphic user interfaces to be utilised in selection process. Program also contains curve fitted values obtained from lab measurements, so after calculating heat loss, it will suggest the best fitting Panel radiator selection available. The basic aim here is to supply a means of optimal radiator selection for a selected room in buildings. Models are intended for the users of small constructors to select appropriate radiators and approximate room heat loss with an easy to use tool
Effects of Twisting Ratio, Diagonal Length, and Pitch Ratio of Hexagonal Pin Fins on Thermo-hydraulic Performance of Heat Sink
No full textWhile the effect of the twisting ratio on a heat sink was investigated for the first part of the study, the diagonal length and pitch ratio were observed for following step. The parametric studies were applied under turbulent regime (2658≤ Re≤7138) to monitor thermo-hydraulic performance of novel proposed design. The edge length of the pin fins (Lef) wasvaried regarding their diagonal length (5≤ Lef ≤ 6) while the pitch ratio (P/e) and twisting ratio were varied in the range of 0.75≤ P/e≤1.0 and 50≤TR≤ 200 respectively. By using the turbulent model SST k-ω with low-Re correction model on ANSYS Fluent, the computational study has been carried out to discretize RANS equations. Average Nusselt number (Nu) and average Darcy friction factor (f) which define the thermo-hydraulic performance of system were elucidated in detail. As a result, the best thermo-hydraulic performance was achieved as 1.55 by using the lowest twisting ratio (TR=200), pitch ratio (p/e=0.75) and the highest diagonal length (Lef=6) and at Re=2658

No full textThe increasing popularity of electric vehicles highlights the importance of power sharing in hybrid renewable energy systems. This article discusses the integration of electric vehicles into hybrid renewable energy systems using the Dandelion Optimizer based optimal sizing method. An amalgamated energy mechanism, which encompasses a solar/wind/battery/electric vehicle grid connection, has been suggested to generate electricity for a university positioned at 40°39.2\u27 N latitude and 29°13.2\u27 E longitude. Two loads have been connected to the system, one is the campus load, and the other is the electric vehicle charging load. Renewable energy sources, such as PV and wind, were utilized in the system. The study shows that four electric vehicles with a capacity of 52.4 kWh from the Turkish automotive manufacturer TOGG can be charged at designated locations on the campus, and the university campus load can be met continuously with a grid-connected hybrid energy system. The comprehensive examination comprises estimation of yearly expenses, energy expenditures, scheduling of electric vehicles, decrease in the consumption of electricity from the primary power grid, and ecological consequences.The entire simulation study was conducted using MATLAB 2022b software

Factors supporting settlement among Syrian refugee women: A longitudinal participatory action research study
No full textIntroduction: Over 13 million Syrians have been forcibly displaced since the start of the Syrian civil war in 2011. In response to this humanitarian crisis, several high-income countries have settled thousands of Syrian refugees. In Canada, over 50,000 Syrian refugees have resettled through varying resettlement programs. Half of the refugees are women who are mothers or of child-bearing age, and who experience numerous health disparities. This article reports findings from a larger, Canadian-based study inquiring into the factors supporting and shaping the settlement and integration experiences among women who are Syrian refugees and mothering. Methods: A longitudinal intersectionality-framed participatory action approach was initiated through multiple meetings with a diverse range of non-profit community organizations focused on refugee health and settlement. Through these meetings, sustainable relationships were formed, and trust was built toward further engaging with the Syrian refugee mothering women population. A core group of 4 women were employed as peer research assistants and were integrated across research processes. Results: In total, 40 Syrian refugee mothering women participated in this study. Six themes emerged from data analysis of their lived experiences of resettlement. Four of these themes are published elsewhere. We focus this article on two of the six key findings: harnessing strength-based capabilities, and peer research assistant experiences. Conclusions: The two findings described in this article convey facilitators that add to understanding influences on the mental well-being of Syrian refugee mothering women. Unique to this study is the novel integration of peer research assistants and a model of support which contributes to an ethical and inclusive approach to understanding lived experiences among refugee women. This article highlights how this model benefits the peer research assistant and promotes community engagement among women.
The Spectator-in-Crisis: Affective Engagement and Political Mimesis in Horror Cinema
No full textThis paper examines the spectatorial engagement with on-screen violence in horror cinema for its potential to evoke both affective and political reactions. By analyzing the works of Sergei Eisenstein, Jane Gaines, and Linda Williams, the study delves into the concept of "political mimesis" through its manifestation in various film genres, particularly in horror. Drawing from Eisenstein\u27s theory of movement and the figure-in-crisis, I argue that the spectator-in-crisis experiences emotional and physical reactions when witnessing grotesque violence in horror films.
Focusing on the affective-corporeal dimensions of horror, as proposed by Xavier Aldana-Reyes, this paper explores the relationship between the viewer and the on-screen bodies. It investigates how horror cinema impacts viewers\u27 bodily responses, emotions, and embodiment. This phenomenon is linked to somatic empathy and sensation mimicry, which enable the viewer to vicariously experience pain and corporeal damage, thus mobilizing affect to facilitate embodiment. This investigation also discusses the role of film techniques, such as montage and framing, in shaping the viewer\u27s reception and emotional affect to highlight how horror aesthetics, audience reception, and affect are relational proxies for analyzing the genre\u27s influence on the viewer\u27s perception of power dynamics, societal issues, and cultural influences.
To illustrate the points made, the paper examines Eisenstein\u27s October: Ten Days That Shook the World (1928) and the horror film Daybreakers (2009), demonstrating how on-screen violence moves the actors and the audience. The paper concludes that cinematic depictions of violence in horror and other genres compel viewers to react, leading to a "full-bodied engagement" to further illustrate the importance of the spectator-in-crisis experiencing turmoil. This investigation into the affective allure of horror in spectatorial engagement broadens the understanding of how on-screen violence influences audience reactions and raises questions about applying these techniques and theories to other film genres.
