The aim of this paper is to investigate numerically the surface roughness effects on the overall performance of parallel flow microchannel heat exchanger (PFMCHE) with different hydraulic diameters. Water has been used as working fluid flow velocities in one direction for hot and cold channels with square shape. Surface roughness considered in this study has been choiced as ratio with equal 0.14 of surface roughness to hydraulic diameter. The obtained results showed that, the pumping power increased with increasing effect of surface roughness and decreasing hydraulic diameter, also the thermal performance increased slightly with increasing surface roughnessDownloads
