Notes:
Finite element method (FEM) was used for planar ablation problem of heat protection materialsbased on thermal analysis. ANSYS, a commercial FEM code, was employed for modeling and calculating,and material deleting and boundary moving problems were solved with its advanced techniques.Various heat flux (HF) densities ranging from 1 to 10 MW/m2 as thermal loads were investigated to theeffects of heat conduction and ablation, respectively. The results showed that a sudden thermal load cancause great temperature rise and high thermal gradient near the surface of the material. The ablativequantity and ablation rate were also calculated, and mathematical models have been deduced for them
