摘要
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。
A numerical analysis was performed to study convective burning flow field
in solid propellant crack.The implicit TVD scheme was used to solve the two dimensional Navier
Stokes equation with gas injection and erosive burning.The pressure distribution inside the crack
was obtained and the relation between the length and height of crack and the pressure in crack tip
was also discussed.
