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 Hc 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.
