| Abstract: | 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. |
