Paper Title:
Flow and Heat Transfer Characteristics in a Channel Periodically Fitted with Blocks and Inclined Plates
  Abstract

A numerical investigation in the CFD method of the heat transfer characteristics and the self-sustained oscillation flow is conducted in a grooved channel with periodic mounted inclined plate.Control of low Reynolds number range(600-1600), two-dimensional, unsteady laminar flow was analyzed .Various physical and flow arrangements have been considered as plate length, plate position and Reynolds number .A comparison among different channels was made for streamlines、history of cartesian velocity component in the x-direction and Nusselt number(Nu).Compared with the results got by the no plates case, the heat transfer has been enhanced in channel that installation of a inlined plate for all Reynolds number.At higher Reynolds number(Reynolds number over the critical Reynolds number), the enhancement of heat transfer is more marked ,that because it can not only modify the direction of the flow towards the obstacle faces to be cooled ,and activate the self-oscillations using inclined plates placed periodically.
