对固体推进剂裂纹内的对流燃烧流场进行了数值模拟，计算采用隐式ＴＶＤ格式求解有加质的二维粘性可压流的控制方程，并且考虑了侵蚀燃烧效应，计算获得了对流燃烧条件下裂纹内部压力分布，讨论了裂纹长度、高度对裂纹尖端压力的影响。
Numerical simulations of the convective combustion flow field in the crack of solid propellant were carried out. The governing equation of two-dimensional viscous pressure-flow with additive mass was calculated by implicit TVD scheme. Considering the erosion combustion effect, the convective combustion conditions Under the crack pressure distribution, the influence of crack length and height on crack tip pressure is discussed.
