The hydrodynamic performance prediction of ship hull with propeller and rudder
In the present study, we conducted ship”s resistance and propulsion performance, using computational fluid dynamics techniques, where a Reynolds-averaged-Navier-Stokes equations (RANSEs) solver was employed.The principal aim of the study is to verify the ability of a CFD method, to predict the hydrodynamic performances of a ship hull appended by propeller and rudder.The complexity in the mesh generation is one of the main obstacles for CFD.For convenience of mesh generation, unstructured meshes were used in the region around ship hull, propeller, and rudder, where the domain”s shape is formed of delicate curved surfaces.On the other hand, structured meshes were generated for the rest of the domain.Following a hybrid mesh generation approach, prismatic cells have been generated in the boundary layer, where viscous phenomena are dominant, and tetrahedral cells in the remaining regions.The SST k-w model has been employed for turbulence closure using the steady-rotating reference frame source terms.Thrust and torque forces, pressure and velocity distributions were used to analyze the computed flow field.The hydrodynamic performance prediction method was gotten and was validated.The computational results were validated by comparing with the existing experimental data.
