  • In order to seek a new method to study the complex flow field of isolator,the influence of flow parameters upon the internal flow field of isolator under different conditions was studied by numerical simulation with coupled double distribution function lattice-Boltzmann method(LBM),and the parameters included the back pressure,entrance Mach number,and boundary layer thickness.The results show that with the increase of the back pressure and boundary layer thickness or with the decrease of entrance Mach number,shock train would move upwards along the isolator.From this study,it can be concluded that the coupled double distribution function LBM is an efficient approach for simulating the complex flow field of scramjet.
