Abstract : This article discusses the selection of the design parameters and the special structural points of the Northwestern Polytechnical Univ low speed, two-dimensional flexible wall self-streamlining wind tunnel. It also introduces the wind tunnel flow field operation, the self-streamlining iterative substitution design, the experimental operation programming, and the initial experimental results. As far as concerns the cylinder model with blockage ratio epsilon = 13.7% and the NACA0012 airfoil zero lift configuration with height to chord ratio of H/c = 1.28, after going through the process of 2-4 iterative substitutions in the self-streamlining model, it is even easier to get convergence and obtain a non-interference value which corresponds with the relevent reference materials and the self-correcting wind tunnels outside China.
