... by subtracting from the total inflow (determined in GBFLOW-3D) the velocities induced by the same propeller ( determined in MPUF-3A). Several iterations between GBFLOW-3D and MPUF-3A are performed until convergence is reached. The three-way interaction among the pod/strut and the two propellers is fully...

... A fully three-dimensional unsteady Euler solver, based on a finite volume approach and the pressure-correction method, is developed and applied to the prediction of the effective wake for propellers subject to non-axisymmetric inflows. The method is coupled with an existing vortex lattice method...

... Various wake alignment techniques which have been developed in the past for the analysis of non-cavitating propellers in uniform inflows are reviewed and some of them are extended in the case of cavitating flows subject to inclined inflows. The effect of the inclined trailing wake geometry...
