Numerical Simulation Of Tip Clearance Impact On A Pumpjet Propulsor, Lin Lu, Guang Pan, Jing Wei, Yipeng Pan

Ocean Engineering and Marine Sciences Faculty Publications

Numerical simulation based on the Reynolds Averaged NaviereStokes (RANS) Computational Fluid Dynamics (CFD) method had been carried out with the commercial code ANSYS CFX. The structured grid and SST keu turbulence model had been adopted. The impact of noncondensable gas (NCG) on cavitation performance had been introduced into the Schnerr and Sauer cavitation model. The numerical investigation of cavitating flow of marine propeller E779A was carried out with different advance ratios and cavitation numbers to verify the numerical simulation method. Tip clearance effects on the performance of pumpjet propulsor had been investigated. Results showed that the structure and characteristics of …
