In this study, pulsating flow of fluid in rough and smooth circular microchannel is investigated numerically. Pulsating flow amplitude (A), frequency (ω), and roughness of microchannel effect on heat transfer and pressure drop are investigated compared with smooth microchannel. Reynolds number (Re = 200) is constant throughout the simulation. Heat transfer performance of circular microchannel and pressure drop is found increasing with increment of pulsating amplitude. However, pulsating flow frequency impact in heat transfer of circular microchannel is found inconsequential. The whole simulation is repeated for three different pulsating flow amplitudes (A) and roughness spacing frequency (s).
