Propeller or thruster open water

  • Simulation of propeller or thruster unit performance in undisturbed inflow over a range of advance velocities (J) and shaft speed combinations, at one or several pitch (P/D) settings.
  • 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.
