Abstract

In the paper new modifications of a large-particle method are given in the appendix to the analysis of gas-suspension currents. It is shown that given modifications allow us to carry out calculations of shock waves behavior in gas-suspensions without introduction explicit artificial viscosity which helps to avoid distortion of a physical phenomenon of gas-suspension current connected with the existence of oscillation. It is shown that given modifications of the large particle method are effective and help to carry out calculations of strong shock waves in gas-suspensions
