| 摘 要： | 本文介绍了一种多角柱体在闭口风洞中的表面压力洞壁阻塞干扰特性的实验研究,其结果表明,柱体表面压力分布的洞壁阻塞干扰与表面相对于来流的方向关系极大,不同表面之间的阻塞干扰量可以出现很大差异,传统的洞壁阻塞干扰修正理论不能简单地用于柱体压力分布试验的洞壁阻塞干扰修正。

| Abstract: | This paper introduces the experimental results of wall blo-ckage effects on pressure distributions of hexagonal prisms in a closedwind tunnel.It is indicated that the wall blockage effects on the pressuredistributions of each surface of the prism are closely related to its direc-tion with respect to the coming flow. There are quite different values ofblockage effects on different surfaces of the model and the traditional the-ories for correction of wall blockage effects should not be straight ap-plied to the tests of pressure distributions on the prisms in the wind tunnel. |
