For the purpose of predicting and improving the performance of water jet devices, mathematic modeling of turbulent cavitating flow is studied and a practical compressible mixture flow method has been developed by coupling a simplified estimation of bubble cavitation and a flexible compressible. The method is applied to the case of high-speed water jets issuing from a submerged nozzle and both no-caviating and cavitating jets under different cavitation numbers are treated.
