Numerical simulation of nosetip shape change during ablation on arc heater

对电弧加热器试验条件下端头的烧蚀外形进行了仿真计算 ,考察了碳 碳端头烧蚀外形随来流条件的变化规律 。

This paper presents a numerical simulation of nosetip shape change during ablation on arc heater. The effect of non uniform jet flow on shape change, as well as the influence of roughness on boundary layer transition and heat increment, was studied thoroughly. Some conclusions were drawn which would be useful for experiment design.
