摘要
通过对N S方程的求解计算了二维圆柱绕流及三维绕钝双锥高超声速流动过程中的气动热问题 .对于求解方程 ,在空间离散的格式上 ,选用了 3种上风格式———Roe的FDS ,VanLeer的FVS和AUSM +格式以及一种中心差分格式 ,将各种格式所得的热流结果与实验结果进行了比较 .对于AUSM +格式 ,还应用了minmodlimiter和双minmodlimiter两种限制器 。
The hypersonic flows around the two-dimension cylinder and three-dimension biconic are simulated by solving the N-S equations with computational fluid dynamics(CFD) method to get the heat transfer rate. For solving the N-S equations, Roe's FDS scheme, Van leer's FVS scheme, AUSM+ scheme and a center scheme are employed. All of the results are compared with the experimental data. For AUSM+ scheme, minmod limiter and double minmod limiter are used and compared with each other.
