Description

In present paper, we investigated the effects of clearance length between a body and a duct wall, and duct height on the heat transfer characteristics and flow behavior at downstream region of body when the blunt body was set in parallel plate duct with some distance separating it from the duct wall as a turbulence promoter. At the ratio of clearance to body height, C/D=0.05∿0.1,the heat transfer was characterized by the reattachment of shear flow separated from the body. Furthermore, the heat transfer depended on both effects of the reattachment flow and the separation vortex at C/D=0.15,and effect of the separation vortex generated by separating flow through the clearance or the side vortex induced by Karman vortex at C/D=0.2 and 0.25.
