| Abstract: | Hydrodynamic performance of waterjet propeller is calculated.On the basis of conservation of mass and conservation of momentum,integral equation of incompressible flow is established.Using SIMPLE(Semi Implicit Method for Pressure Linked Equations) as basic calculating method combined with velocity-modified equation and pressure-modified equation,inner velocity field and pressure field of waterjet propulsion are solved.Turbulent model of waterjet propulsion is studied by using RANS(Reynolds Averaged Navier-Stokes).Three dimensional model of waterjet propulsion is founded and composite grid distribution method is adopted to improve calculating precision.Relationship between discharge and head,power,efficiency is analyzed. |
