The invention discloses a waverider effect evaluation method based on waverider factors. The waverider effect evaluation method comprises the steps that a waverider hypersonic shock wave flow field is obtained; voxelization is carried out on the wave rider hypersonic shock wave flow field, and the pressure gradient of each voxel is obtained; substituting the pressure gradient of each voxel into a Lovely-Haimes algorithm formula to extract a contour surface in the flow field, namely a shock wave surface in the flow field; removing noise from the shock wave surface in the flow field to obtain a denoised shock wave surface; fairing the denoised shock wave surface by adopting a Laplace algorithm to obtain a final flow field shock wave surface; projecting a preset wave rider front edge line to the final flow field shock wave surface to obtain a front edge surface, and obtaining the leakage rate of the front edge surface; and obtaining a waverider factor according to the leakage rate of the front edge surface. The invention provides a quantitative waverider effect evaluation method which is used for evaluating the influence of flight environment change and appearance change on the waverider effect of the waverider.
本发明公开了一种基于乘波因子的乘波效应评估方法,包括:获得乘波体高超声速激波流场;对乘波体高超声速激波流场进行体素化,得到每个体素的压力梯度;将每个体素的压力梯度带入Lovely‑Haimes算法公式提取流场中的等值面,即为流场中的激波面;对流场中的激波面进行去除噪声得到去噪声后的激波面;对去噪声后的激波面采用拉普拉斯算法进行光顺,获得最终流场激波面;将预设的乘波体前缘线投影到最终流场激波面上得到前缘面,并得到前缘面的泄漏量;根据前缘面的泄漏量得到乘波因子。本发明提供了定量的乘波效应评估方法,评估飞行环境改变以及外形变化对乘波体乘波效应的影响。
