INVESTIGATION ON CORRECTION OF TUNNEL WALL INTERFERENCE FOR DYNAMIC AIRFOIL TEST IN LOW-SPEED WIND TUNNEL
Y. Jiao, China; H. Zou, China; B. Chen, China; C. Xiao, China
Three kinds of correction methods for the wall interference of the dynamic airfoil wind tunnel test are proposed: 1. Experimental method; 2. Numerical simulation correction method; 3. The correction method based on the principle of image system and wall pressure signature method. The first two methods are easy to implement and give correct results, but are not easy to use in usual experiments. The third method is easy to apply, the workload is small, and the results are correct, but it still needs further research and improvement.
