基于马赫数分布规律可控的轴对称基准流场,使用流线追踪和截面渐变方法设计了进口截面形状非对称的类水滴形进口转圆形出口高超内收缩进气道,研究了设计参数横向位置d,纵向位置h和进口形状曲线参数a对性能的影响规律。在相同约束条件下对比了类水滴形进口进气道与常规矩形转圆、方形转圆进气道的性能差异。结果表明:在设计点,所研究的设计参数对类水滴进口进气道总体性能影响显著;在捕获面积和内收缩比相同的情况下,类水滴进口进气道综合性能明显优于常规矩形转圆、方形转圆进气道。
Based on the controllable axisymmetric reference flow field with Mach number distribution law, the inlet cross section with asymmetric inlet cross section was designed by using the flow line tracing and cross section gradient method. The position d, the longitudinal position h and the curve of the inlet shape parameter a on the performance of the law. Under the same constraint conditions, the performance differences between the inlet of a drop-shaped inlet and that of a conventional rectangular round and square round inlet were compared. The results show that at the design point, the design parameters studied have a significant effect on the overall performance of the inlet of the water droplet. Under the same catching area and internal shrinkage ratio, the comprehensive performance of the water inlet of the droplet is obviously better than that of the conventional rectangle Round, square round inlet.
