| 摘 要： | 本文用有限元素法对半圆形腔壁表面的冲击流动和对流换热作了数值计算, 由于引射作用在腔内会出现回流, 使得流动结构和换热系数的分布与大空间的冲击流动存在明显的区别。计算结果表明, 除在冲击缝两侧壁面附近有第一回流区外, 在一定流动条件下还可能在下游产生第二回流区。

| Abstract: | Calculation for two dimensional flow and heat transfer of impingement in a semicircular closure has been completed with a Finite Element Method.It is found that the impinging flow in closure is much different from the impingement in free space.Except the circulations on the two sides of inlet nearby the inner wall,it is possible to induce two contrary circulations nearby the out wall in down stream.The effects of the currents on isotherm and heat transfer are given graphically. |
