Combined Geometrical Optimisation of a Square Microchannel with Smoothed Corners
Marco Lorenzini,
Nicola Suzzi
Abstract:Several engineering systems currently use microchannel heat sinks. In order to increase the performance of these devices, optimisation according to the first and second law of thermodynamics is employed. One way to achieve the goal is to modify the geometry of the cross-section, as is done in this paper for square ducts, having the walls at a uniform temperature which is higher than that of the bulk fluid at the inlet. The effects of both the thermal entry region of the duct and the heat generation due to visc… Show more
