在双流体模型基础上，应用时间分裂法将ＴＶＤ格式和ＭａｃＣｏｒｍａｃｋ格式分别应用于气相和颗粒相方程，对非定常含尘反应激波进行了数值模拟。讨论了马赫数为６．０时激波传入玉米粉尘－氧气混合物后压力波的发展过程，并与实验现象进行了比较，两者符合较好。 Based on the two-fluid model, the TVD and MacCormack formats are applied to the gas-phase and particle-phase equations separately by time splitting method, and the unsteady dust-bearing reaction wave is numerically simulated. The development of pressure wave after the shock wave was introduced into maize dust-oxygen mixture at Mach 6.0 was discussed and compared with the experimental phenomenon, which is in good agreement.
