两个角区湍流场及其尾迹的实验研究

绕两个翼型－平面的角区流动及其尾迹的实验是在低湍流度风洞中完成的．在零攻角条件下，对翼型－平面的角区流场内诸参数，如翼型表面和平板面上的压力分布、绕翼型及尾迹区内的平均速度、脉动速度、湍动能、二阶关联量ｕ′ｖ′及ｕ′ｗ′进行了广泛的测量．通过对比，分析了这两种模型与平面所构成的角区及其尾迹区内的流动特性

EXPERIMENTAL INVESTIGATION OF TWO TURBULENT WING BODY JUNCTIONS AND WAKES FLOW

The experimental studies on two wing body junctions and wakes were carried out in a low turbulence level wind tunnel. Intensive measurements of various flow parameters in the flow field around the wing body junction,such as the distribution of the pressure along the airfoil and plate wall,the mean and fluctuation velocity, as well as the turbulence energy, u′v′ and u′w′ etc., are presented. Through comparation of two junction flow fields, some features are analysed.
