Numerical investigation for coupled rotor/ship flowfield using two models based on the momentum source method

The coupled rotor/ship flowfield is investigated using the Navier–Stokes solver when the helicopter rotor hovers in the ship’s airwake. The solid rotor model (SRM) and virtual rotor model (VRM) are employed, considering the different types of rotor simulation by the momentum source method. Qualitati...
