摘要

为改善内埋式弹舱流场特性,采用具有倾角的弹舱后壁。数值模拟同一来流情况下不同后壁倾角舱内的流场,分析不同后壁倾角对弹舱流场特性的影响。研究结果表明:采用带后壁倾角的开式空腔,其空腔流动类型仍为典型的开式空腔;随着后壁倾角的增大,能有效改善舱内流动特性。

关键词： 内埋弹舱; 后壁倾角; 空腔流场; 数值模拟

Abstract

A cavity with some rear wall obliquity was used to improve the characteristics of the cavity's flow field. Simulating characteristics of the cavity's flow field on the same flow with different rear wall obliquity were got and the effect on the characteristics of the cavity's flow field with different rear wall obliquity was analyzed. The results indicate that the effect of rear wall obliquity can improve characteristics of the cavity's flow field. Meanwhile, the style of the flow is still the open cavity flow.

Key words： internal weapon bay; obliquity of rear wall; cavity flow; numerical simulation
