3D rendering of a ship’s hull fitted with twin propellers and rudders, with colour contours illustrating water flow pressure around the propeller hubs

Hull resistance and nominal wake

Bare hull simulation with the hull (and appendage) geometry but without propeller(s).
Prediction of hull resistance (P_E) at certain ship speeds and drafts for hull lines optimisation.
Prediction of nominal wake field for optimisation of propeller inflow and input to propeller design.
The method calculates the free water surface and wave resistance using 2-phase (water and air) flow, steady state RANS and SST-kΩ turbulence model.
