... ratio which generates the lowest entropy generation rate. It indicates that decreasing the aspect ratio contributes to the reduction of entropy generation by heat transfer, because smaller channel width allows for less heat transfer rate. In contrast, decreasing the aspect ratio contributes the pressure...

... The entropy generation rate has become a useful tool for evaluating the intrinsic irreversibilities associated with a given process or device. This work presents an analytical solution for entropy generation in hydrodynamically fully developed thermally developing laminar flow in a microtube...

... The issue of entropy generation in laminar forced convection of a Newtonian fluid through a slit microchannel is analytically investigated by taking the viscous dissipation effect, the slip velocity and the temperature jump at the wall into account. Flow is considered to be hydrodynamically...
