Abstract
Abstract Thermal management of equipment is a very crucial step for optimum operation. This study is aimed at modifying the shape of traditionally circular electronic components to enhance their thermal-hydraulic performance. The frontal portions have been replaced with different profiles of conic sections such as parabola and hyperbola to understand the influence of frontal modification on fluid dynamics and heat transfer. The study has been carried out for confinement of 4d to mimic the confined fluid environment as in electronic chambers and the Reynolds numbers considered range from 60 to 500. The numerically simulated data were postprocessed and elucidated with the help of contour plots, various drag coefficients, total pressure drop, Strouhal number, and Nusselt number. The results claim that hyperbolic front with rear segment offers the best heat transfer with an improvement of 5.78% as compared to circular components, whereas the parabolic front has the best thermal-hydraulic performance. Parabolic profile reduces drag by 2.66% and improves heat transfer by 4.14%.
