Thermal and hydraulic characteristics of nanofluid in a triangular grooved microchannel heat sink (TGMCHS)

A numerical simulation is conducted to examine the heat transfer and fluid flow characteristics of nanofluids in a triangular grooved microchannel heat sink (TGMCHS). The governing and energy equations are solved using the finite volume method (FVM). The influence of the geometrical parameters such...
