本文简要介绍西北工业大学低速二元柔壁自流线型风洞的设计参数选择与结构特点,空风洞的流场性能、自流线型迭代方案,试验运行程序和初步试验结果。 对于堵塞比ε=13.7％的圆柱体模型和高弦比H/c=1.28的NACA0012翼型零升状态,经2～4次自流线型迭代过程便可收敛得到与国外自修正风洞和有关参考文献一致的无干扰值。 This paper briefly introduces the design parameters and structural characteristics of the low-velocity bivoltine self-flowing wind tunnel of Northwestern Polytechnical University, the flow field performance of the wind tunnel, the self-streamlined iteration scheme, the test operation procedure and the preliminary test results. For the cylinder model with blockage ratio ε = 13.7% and the zero-rise state of NACA0012 airfoil with a high string ratio of H / c = 1.28, self-correcting wind tunnels and related references can be converged after 2 to 4 iteration processes Document consistent non-interference value.
