Research Abstract

This work has been performed on purpose to establish a practical CFD method for the numerical simulation of high-speed submerged water jets as well as the hydrodynamic design of jet nozzles. The main results can be summarized as follows: (1) A compressible mixture flow method based a simplified estimation of bubble cavitation is established. (2) A modification on the eddy viscosity of cavitating flow is proposed considering the effect of bubble expanding and contracting. (3) Numerical simulation of turbulent activating jets issuing form submerged orifice nozzle were carried out and the reliability of present method has been verified experimentally. (4) A new sheathed orifice nozzle is developed and its property has been evaluated via visualization experiment.
