An Euler solver, based on a finite volume approach, 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 lifting-surface vortex-lattice method for the analysis of unsteady cavitating propeller flows. An axisymmetric and a fully three-dimensional version of the method are presented. The results are validated against analytical solutions from potential flow and actuator disk theory. The effect of the grid parameters on the results ( circumferential average and amplitudes of harmonics of the predicted effective wake) is found to be very weak. The predicted total velocity field correlates very well with that measured in propeller experiments in axisymmetric flow.
