| Abstract: | In the present paper, a two-fuid model with interphase coupling effects is applied to dilute gas-particle systems. In order to study the characteristics of shock diffraction around a sharp 90 degree corner in the dusty gas,we adopt the operator-splitting technique and high-resolution numerical method, reveal the changes of diffraction pattern due to particle and discuss the effects of particle properties on post-shock flow field. |
