Hull resistance and nominal wake
- Bare hull simulation with the hull (and appendage) geometry but without propeller(s).
- Prediction of hull resistance (PE) 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.
