Simulation and Application of a New Multiphase Flow Ablation Test System for Thermal Protection Materials Based on Liquid Rocket Engine

Internal flow field ablation is an important issue in thermal protection materials for rocket engines and hypersonic vehicles. In this paper, a new multiphase test system, with Al2O3 particle delivery device based on oxygen-kerosene liquid engine, designed manufactured. A general variable-precision modular system simulation method proposed to analyze the dynamic characteristics of system. addition, unique internal was performed 4D C/C composite simulating working conditions SRM. The results show that can provide wide temperature range (756~3565 K) pressure (0.2~4.2 MPa). multi-disciplinary helpful more accurate design analysis, maximum error less than 5%. tests line rate nozzle at 3380 K 1 MPa 0.053 mm/s, verifying combined effect thermochemical mechanical ablation. environment controllable, which provides effective way materials. has reference value related engine.
