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。 In this paper, the circumferential pressure distribution and the corresponding wall pressure information of the two-dimensional cylindrical model with blockage ratio of 10%, 25% and 33% were respectively measured in the low-speed wind tunnel. Then the wall pressure integral method was used to modify the wall interference, The results show that the correction method is simple and accurate, and satisfactory correction results are still obtained when the blockage ratio is 33%. This method has good practical value for the study of tunnel wall wind tunnel interference.
