| Abstract: | According to the Lagrange discrete phase model of multiphase flow,mathematical model of the abrasive water-jet(AWJ)nozzle based on the multi-phase movement was introduced,then the boundary conditions was determined and the liquid-solid turbulence which is isothermal,can not be compressed and steady-state in the cone-cylinder nozzles of the export of the pre-mixed AWJ was simulated applying the software FLUENT.The results showed that:the axial velocity and dynamic pressure of the continuous phase in the nozz... |
