| Abstract: | In this paper, the attenuation of planar shock waves propagating into a dusty gas in a uniform cross-section channel generated by two-phase relaxation is investigated, using an operatorsplitting technique and numerical methods with high resolution. Through analyzing the numerical results,the analytic expression of the attenuation law of planar shock waves is developed in which the effects of all physical properties of solid particles on shock attenuation are included. |
