Euler/Euler theory and application of fluid-particle two-phase jet

High Pressure abrasive waterjet is a typical fluid-particle two-phase jet, it is widely used in many industries. In this paper, abrasive particle phase is treated as a continuum, both fluid phase and particle phase are handled in Eulerian framework, numerical simulation of submerged flow field outside a convergent nozzle is performed and the flow field characteristics are studied. Numerical results are compared with experimental results, and good agreements are achieved.
