A Porous-Medium Approach for the Thermal Analysis of Microchannel Heat Sinks
No full textThis paper presents an original method for using the commercial code Ansys Fluent for the thermal
analysis of microchannel heat sinks based on the porous-medium approach and the local thermal
non-equilibrium model. What is new is how heat transfer at the solid porous matrix boundaries is
accounted for, because with the original code those boundaries can only be treated as adiabatic. The
sample application concerns a double-layered cross-flow microchannel heat sink
An efficient artificial compressibility (AC) scheme based on the characteristic based split (CBS) method for incompressible flows
No full textForced convection heat transfer within a moderately-stenosed, patient-specific carotid bifurcation
No full textPurpose - The purpose of this paper is to numerically model forced convection heat transfer within a patient-specific carotid bifurcation and to examine the relationship between the temperature and wall shear stress.Design/methodology/approach - The procedure employs a parallel, fully explicit (matrix free) characteristic based split scheme for the solution of incompressible Navier-Stokes equations.Findings - The arterial wall temperature, rather than the blood temperature dominates the regions of low wall shear stress and high oscillating shear stress. Additionally, negligible temperature gradient was detected proximal to the arterial wall in this locality.Originality/value - The presented results demonstrate a possible mechanism for cold air temperature to influence the atherosclerotic plaque region proximal to the stenosis. The proposed patient-specific heat transfer analysis also provides a starting point for the investigation of the influence of induced hypothermia on carotid plaque and its stability
Perspectives on Sharing Models and Related Resources in Computational Biomechanics Research
Full text linkThe role of computational modeling for biomechanics will be increasingly prominent. In computational biomechanics, model sharing can facilitate assessment of reproducibility, and can provide an opportunity for repurposing and reuse, and a venue for medical training. The community's desire to investigate biological and biomechanical phenomena crossing multiple systems, scales, and physical domains, also motivates sharing of modeling resources as blending of models developed by domain experts is anticipated. The goal of this article is to understand current perspectives in the biomechanics community for the sharing of computational models and related resources. Opinions on opportunities, challenges, and pathways to model sharing, particularly as part of the scholarly publishing workflow, were sought. A synthesis of these opinion pieces indicates that the community recognizes the necessity and usefulness of model sharing. There is a strong will to facilitate model sharing and there are corresponding initiatives by the scientific journals. Outside the publishing enterprise, infrastructure to facilitate model sharing in biomechanics exists and simulation software developers are interested in accommodating the community's needs for sharing of modeling resources. Encouragement for the use of standardized markups, concerns related to quality assurance, acknowledgement of increased burden, and importance of stewardship of resources are noted. In the short-term, it is advisable that the community builds upon recent strategies and experiments with new pathways for continued demonstration of model sharing, its promotion, and its utility. Nonetheless, the need for a long term strategy to unify approaches in sharing computational models and related resources is acknowledged
