FLOW AND HEAT TRANSFER CHARACTERISTICS IN A CHANNEL OBSTRUCTED BY A SQUARE ROD MOUNTED IN ASYMMETRIC POSITIONS

要約

A two-dimensional numerical computation has been made for the flow and heat transfer in a channel obstructed by a square rod. In order to investigate the effect of the displacement of the rod on the flow and heat transfer characterictics, the rod is displaced from the center plane of the channel. The displacement of the rod position from the center plane of the channel, e, and the rod size, d, are changed in several steps. The channel Reynolds number is also changed within the range from 500 to 1,500 where flow should be steady laminar if the rod is removed.
When the ratio e/H becomes larger, the flow tends to be less unstable. Heat transfer from both walls decreases remarkably when flow returns to be steady. Even at e/H ratio when flow is still destabilized, the enhancement of the heat transfer due to the flow unsteadiness is not remarkably observed. In those cases, the flow unsteadiness does not generate vorticity island exerting a noticealbe washing action on the wall which was observed in the cases when the rod is located in the center plane of the channel. Thus, the displacement of the rod is concluded not to be so effective on the augmentation of heat transfer from the walls.
