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.
