Numerical Simulation of Cylindrical Interface Instability by Using Multicomponent Gas Kinetic Scheme
摘要
Abstract
Air/He and air/R22 cylindrical interface instabilities were calculated by gas kinetic scheme (GKS) under the assumption that the components have the same temperature and velocity in the cell.The density dis-tributions at different time,the displacement histories and the average velocity of characteristic points at the interface were obtained.The displacements of characteristic points increased with time gradually when the shock wave passed through the interface.The average velocities of characteristic points agreed with the results of previous experiments and numerical simulations very well.The comparisons between the simulation results and literature data suggest that the GKS which is based on the particles movement has a good simulation per-formance for the cylindrical interface instability.关键词
