Water jet propulsion

WJ Vessel Simulation

  • Self-propulsion simulation using body force pump model or sliding mesh technique with the real pump geometry represented.
  • 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.
  • Prediction of:
    • Vessel performance and WJ-hull interaction effects.

WJ System Simulation

  • WJ system simulations of inlet, pump unit and steering and reversing unit (SRU).
  • Prediction of:
    • Pump wake.
    • Potential cavitation in inlet and pump.
    • Steering and reversing unit forces.
