Abstract

The calculation method of thermal chemical ablation was discussed in the paper. Numerical simulation of high temperature thermal chemical ablation for carbon composite material was done and the ablation results were calculated. The processes of oxidation and sublimation were appeared in the ablation for carbon composite material. The alternant temperature of oxidation and sublimation was 3300K under 10 atm. The alternant temperature would raised when pressure raised. The result of oxidation was CO. The result of sublimation was C₃ and C₁ gradually. The main reaction was 2C + O₂→2CO under 3300 K. The main reactions were 3C + O₂→2CO, 2C + N₂→2CN and i(C)→C_i (g), i = 1, 3 above 3300 K. The results were consistent with that of spectrum diagnoses, which confirm the valid of thermal chemical calculation by minimum free energy method further.
