Effect of geometrical parameters on boiling heat transfer and pressure drop in micro finned micro gap

Micro gap heat sinks are potential candidates of evaporative cooling. Additional fins in micro gap enhance heat transfer rate by increasing surface area and generating turbulence. The scope of this paper is to numerically investigate the influence of various geometrical parameters on thermal and hyd...
