Numerical study of heat transfer Enhancement in microchannel heat sink With fan shaped cavities different ribs and secondary channels

Abstract

In the present study, detailed numerical simulations of liquid flow in a microchannel heat sink with four different geometry of ribs: rectangular (RR), backward triangular (BTR), forward triangular (FTR), and diamond (DR) arranged symmetrically inside reentrant fan shaped cavities (FC) on side walls has been conducted and compared with smooth channel (SC), to acquire fluid flow and heat transfer characteristics between Reynolds numbers of 136and#61485;588. newline
