Propeller or thruster open water
- Simulation of propeller or thruster performance is carried out in undisturbed inflow conditions across a range of advance velocities (J) and shaft‑speed combinations, using one or several pitch settings (P/D).
- Prediction of propeller open water characteristics (KT, KQ, η0) for propeller design performance prediction and optimisation.
- Fully viscous RANS method using SST-kΩ turbulence model.
- A hybrid mesh technology with wall function. Y+ values at full-scale of 30-60 and at model-scale of approx. 1 to ensure adequate near wall treatment.
- The mesh size is less than 10 million cells with the majority of the cells are located close to the propeller.
