| 摘 要： | 本文建立了激波卷扬煤尘的气固湍流边界层方程,其中考虑了气固两相间的耦合效应和气固相湍流效应。模型认为颗粒上扬是激波后气固流动的剪切升力和湍流效应的结果。数值计算结果与文献实验结果较一致。

| Abstract: | In this paper,a turbulent model is presented for the boundary layer of gas-coal dust flow entrained by a shock and the effects are studied of the turbulen and two phase coupling between gas and solid. The model siginifies that the ingestion of coal dust particles is attributable to the effects of the shear lifting force and turbulent diffusion in the boundary layer of gas-dust mixture flow following the hock. The results of numerical simulation by the present model quite agree with the results of the experiments reported in the papers |
