HEAT TRANSFER AUGMENTATION OF MIXED CONVECTION THROUGH VORTEX SHEDDING FROM AN INCLINED PLATE IN A VERTICAL CHANNEL CONTAINING HEATED BLOCKS

Abstract

A numerical analysis is made of the unsteady flow and heat transfer characteristics of mixed convection in a vertical block-heated channel with and without installing an inclined plate above an upstream block. Parameter studies including the inclined plate angle, Reynolds number (ranging from 260 to 530), and Grashof number (in the range of 0-3,200,000) on heat transfer performance have been explored in detail. The results show that the installation of an inclined plate in the vertical block-heated channel can effectively augment the blocks' heat transfer performance in the channel.
