Three-dimensional numerical investigations on flow and heat transfer for flow past a channel confined square cylinder

Abstract

Present work investigates three-dimensional fluid flow and heat transfer for flow past a square cylinder built-in a rectangular channel. The governing equations for viscous fluid flow and heat transfer are solved numerically with the help of an indigenously developed computational code based on modified MAC algorithm. Unsteady computations are performed for Reynolds number in the range of 400-1000 and channel height ranging from 0.5d to 3d (d being side of the square cylinder). The effect of channel height on onset of vortex shedding, other flow characteristics and heat transfer from heated solid surfaces has been presented.
