| Abstract: |
| The single-velocity and multi-component computing method of multi-fluid dynamic equations are not closed,so we should give out some closure models.In this paper,the closure model named "pressure increment equality" is described,and then we point out its strongpoints and limitations.Based on the pressure increment equality closure model,we give a betterment of it which is aimed at its limitations.By using new closure model,the explosion-drived problem was simulated,the results proved that new closure model can trace the material interface and the shock wave interface much exactly without the vibration on pressure and energy. |
