圆柱绕流洞壁干扰修正研究

The Corrected Investingation of wall Interference on Cylinder Flows

本文对阻塞比分别为１０％、２５％和３３％的二维圆柱模型在低速风洞中测量了其周向压力分布及相应的壁压信息，然后用壁压积分法进行洞壁干扰修正，结果表明修正方法简捷精确，在堵塞比为３３％时仍获满意的修正结果，对风洞实验洞壁干扰研究具有很好的实用价值。

The circumference pressures of three 2-D cylinder modlesand the responsible wall pressures were respectively measured, the modelblockage ratios were 10%, 25,33%respectively,then the non-interferencedata were computed by using the method of wall pressure integration;itshows that the integral method was simple and accurat, to blockage ratio33%,the satisfied result was also gained; it is of very good practicalvalue for wall interference correction
