摘要:
基于炭基和硅基防热复合材料的烧蚀机理对C/C-SiC防热复合材料进行烧蚀分析.依据相变原理,在热传导方程和能量平衡原理的基础上,建立了一维非稳态烧蚀数值模型,模拟了C/C-SiC防热复合材料的烧蚀过程,分析结果与实验数据吻合良好.同时通过数值对比看出,在同等的烧蚀环境中,C/C复合材料的烧蚀速率最快,材料内部温度最低; SiC复合材料的烧蚀速率最慢,但材料内部的温度最高; C/C-SiC防热复合材料充分发挥了C/C复合材料和SiC复合材料烧蚀性能的优越性,在确保烧蚀速率较低的同时,材料内部温度不是很高.
Abstract:
According to the phase transition theory, based on the ablation principles of carbon-base and silicon-base composites, the thermal conduction equation, and energy balance principle, one-dimensional non-steady ablation model is established and the ablation of the C/C-SiC thermal protection composites is simulated. The results of numerical simulation are in good agreement with the data of experiments. The results of numerical simulation show that, in the same ablation environment, for the C/C composites the ablative velocity is the highest and the temperature inside the material is the lowest, while in Sic composites the velocity is the lowest and temperature is the highest. C/C-SiC thermal protection composites combine the advantages of C/C composites and SiC composites, which has lower ablative velocity and lower temperature.
