摘要
A numerical methodology has been developed to simulate the overall ablation process of the insulator material named ethylene-propylene-diene monomer. Special attention is focused on the char layers of ethylene-propylene-diene monomer formed in different ablation environments by analyzing the characters of the char layers, which was defined as an uneven porous medium. An overall ablation model has been developed to describe the simultaneous thermo-chemical ablation and particle erosion of ethylene-propylene-diene monomer using porous medium equation methodology. A total of six calculations of one kind of ethylene-propylene-diene monomer material have been performed to obtain the theory erosion properties in two lab-scale solid rocket motors, and all the submodels of overall ablation model have been validated.
