摘要
Abstract
In order to investigate the influence of cavity configuration on detonation initiation via shock wave focus, detonation initiation with different size cavities and different curvature cavities were simulated, hydrogen-air mixture was used.The results indicate that choosing cavity size should counterpoise both jet intensity and attenuation of incidence shock wave caused by cavity vacuum.Cavity curvature neither too big nor too small.In this article, the performance of portion sphericity cavity with diameter of 74mm is best.关键词
