Ablation of insulator under particle erosion conditions is an intense transient process which is affected by plenty of factors.Transformation of the insulator surface and erosion parameters of partial two-phase flow are interactional.Based on ablation experimental system,experimental investigation(case 1 and 2)has been conducted to study the effect of different initial erosion parameter of two-phase flow on ablation process and ablation result.Numerical simulation was used to analyze the experimental proces...

0引言绝热层是固体火箭发动机的重要组成部分。由高温燃气中颗粒对绝热层的强烈冲刷作用所引起的发动机失效问题在导弹飞行试验中屡有发生。针对这种问题,国内外学者进行了大量研究。其中Yang B C和Cheung F B[1-2]综合考虑了粒子侵蚀及热化学烧蚀对绝热层的热作用;Koo J H等[3
