本文研究了燃烧室壁面形状对撞壁射流气体沿壁发展过程的影响。实验发现：射流气体撞壁后主要沿壁面发展，近壁区域会形成浓混合气层，并且混合很慢。本文提出两种方法：１）在壁面设置矩形凹槽，并且利用环境的气流运动加快射流气体的混合；２）在壁面上设置条形障碍物，使射流气体脱离壁面形成空间流动。另外，本文也模拟了ＯＳＫＡ－Ｄ燃烧系统中燃油撞壁后的发展过程。
This paper studies the influence of combustion chamber wall shape on the development of jets wall jet gas along the wall. It is found experimentally that the jet gas mainly develops along the wall after it collides with the wall and forms a dense mixture layer in the near wall, and the mixing is slow. In this paper, two methods are proposed: 1) Rectangular grooves are provided on the wall surface, and the airflow of the environment is used to accelerate the mixing of the jet gas; 2) Barriers are provided on the wall surface to separate the jet gas from the wall surface to form a space flow. In addition, this article also simulates the OSKA-D combustion system in the fuel after the collision wall development process.
