对超高温热化学烧蚀的计算方法进行了研究,对碳基复合材料在不同环境下热化学烧蚀过程进行了数值模拟,对烧蚀产物进行了计算.计算表明,碳基复合材料在烧蚀过程中依次出现氧化、升华过程.10atm下,氧化、升华过程交替温度为330K.压力升高,交替温度也依次升高.氧化产物为CO,而升华产物依次为C3、C1.在3300K以下,烧蚀主反应为2C+O2→2CO.在3300K以上,烧蚀主反应为:2C+O2→2CO,2C+N2→2CN,i(C)→Ci(g)i=1,3.并用哈尔滨工业大学研制的"星形"等离子发生器及国产的等离子体火炬进行了碳基复合材料烧蚀实验.实验光谱检测结果与超高温热化学烧蚀计算的烧蚀产物一致,验证了超高温热化学烧蚀计算的正确性.
