Self-propulsion simulations used for prediction of delivered power to the propeller (PD), propeller shaft speed (n) and propulsor-hull interaction coefficients (WT, t, ηR).
The hull is free to move in trim and sinkage and the method calculates the free surface and wave resistance using 2-phase (water and air) flow, transient RANS and SST-kΩ turbulence model.
The simulation can be donewithfixed trim and sinkage and without hull waves for quicker relative comparisons.
Through an automated simulation setup different design alternatives can quickly be relatively compared for:
Comparison of different propulsion systems.
Optimisation of propeller rotational direction, neutral rudder angles (toe in/out) or thruster orientation (tilt and toe out).
Thruster-thruster interaction or thruster-hull interaction (e.g. nozzle tilt).
