采用耦合的双分布函数格子Boltzmann方法模拟超燃冲压发动机中隔离段的流动.计算结果反映了隔离段内流场的基本结构,表明LBM在隔离段的模拟中是一种具有潜力的数值计算方法.
Flowfield in a constant area isolator is numerically simulated with coupled double distribution function lattice Boltzmann method(LBM).Numerical results reflect general structure of flow field which means that LBM is a potential computational fluid dynamics method.
