摘要
本文提出了一种以洞壁附近控制面上实测的静压分布作为边界条件进行高速风洞大迎角实验洞壁干扰修正的方法。文中介绍了壁压测量、洞壁、模型及尾流的模拟等关键技术。一个实际算例表明本方法较为准确可靠,可应用于模型堵塞度不太大、迎角α≤25°、洞壁附近流动为亚临界的矩形透气壁试验段洞壁干扰的修正。
A method, in which wall interference correction for model tests at high angle of attack in high speed wind tunnel is conducted with static pressures measured on the control surface near the walls as the boundary conditions, is presented. The measurement of wall pressures and the simulation of walls, model, wake and separations are detailed in the paper. A practical example shows that the present method is accurate and effective. It is applicable to wall interference correction in rectangular test section with perforated wall at following conditions: the block-age of model is not too large; the angle of attack is not greater than 25°; and the flow near the walls is subcritical.
