Abstract—

The results of an experimental wind-tunnel investigation of the plate surface heating in the strong viscous-inviscid interaction regime are presented. It is shown that In the presence of a wedge mounted in the vicinity of the trailing edge of the plate the temperature distribution over the plate surface ahead of the wedge considerably changes up to the leading edge, as compared with the case of flow past the same plate in the absence of the wedge. The boundary layer flow is not steady, since during the run the surface temperature grows continuously, the temperature distribution itself along the plate surface being variable. It is established that in an unsteady boundary layer the upwind propagation of pressure disturbances produced by a thin wedge is fundamentally different in nature from the disturbance propagation in the case of flow past a plate with a constant surface temperature.

强相互作用下压力扰动对板表面加热的影响

摘要-

给出了在强粘性-不粘稠作用下板表面加热的风洞实验结果。结果表明，在流过板的后缘附近存在楔形物的情况下，与流过该楔形物的情况相比，在楔形物之前的板表面上的温度分布直至上升缘都发生了很大的变化。在没有楔块的情况下安装板。边界层流动不稳定，因为在运行过程中表面温度持续增长，沿着板表面的温度分布本身是可变的。
