摘要
对常物性流体在通道内的周期性充分发展层流对流换热特性进行了二维数值计算分析 ,所研究的通道是由两平行平板和交错布置于两平行平板上的多个三角形阻流件构成 .讨论了不同Pr数和不同Re数下阻流件高度、顶角和间距对换热系数的影响状况 .
Periodically fully developed fluid flow in a two dimensional passages are numerically analyzed for constant property laminar flow. The passage is formed by two parallel plates with baffles staggered on the two plates. Computations are carried out for different geometric parameters, Prandtle numbers and Reynolds numbers. The influences of Re, Pr, baffle height, angle and the distance between two baffles on heat transfer characteristics are discussed in detail.
