摘要
低速风洞测试干扰主要有2种干扰:一种是洞壁干扰,一种是安装支架干扰。以Suboff潜艇模型为例,通过数值模拟的方法验证了洞壁干扰效应和支架干扰效应对阻力测定试验结果的影响。同时验证了低速风洞试验经典的映像修正法和镜像修正法的可靠性,运用该方法对风洞试验的数值仿真结果进行有效的修正。
The wind tunnel wall and the mounting frame are two main interference effects in the low speed wind tunnel test. The influence of the wall interference and the support interference on the resistance test results are verified through numerical simulation by using Suboff model. Meanwhile, the reliability of the classic image method for low-speed wind tunnel tests was verified. Wind tunnel test numerical simulation results have been effectively corrected by the method.
