Abstract

In this paper, TURBULENT FLOW and HEAT TRANSFER inside a channel with semicircle, triangular and rectangular ribs is simulated numerically. The upper wall is set to be adiabatic, while the lower one is in constant temperature. The problem is investigated for Re=34000. Standard k-ε model is employed for turbulence modeling. The results are presented for different rib geometries. The obtained results show that ascending the ribs height leads to increase in Nusselt number and the recirculation zones. Furthermore, the HEAT TRANSFER rate increases with the strength and the size of the recirculation zones behind the ribs.
