.... The effects of viscosity on the effective wake and on the performance of the propeller blade, as well as on the predicted duct forces, are assessed. The prediction of the performance for those ducted propellers from the present method is validated against existing experimental data. effective wake...

... Software developed at the Massachusetts Institute of Technology for the unsteady propeller analysis and effective wake calculation has been transitioned to the Naval Surface Warfare Center, Carderock Division. The lifting surface propeller software is designed to be coupled with a three...

... in this paper. Also, to demonstrate the predictive capability of the method, simulations were carried out for the series 60 ship hull with a single propeller and a contrarotating propeller under model and full scale conditions. effective wake calculation scale case ship hull ship research ran mpuf3a...

... inside the flow domain and then solves the Euler equations with respect to the total velocity field and pressure. By subtracting the propeller-induced velocities, from the total flow, the "effective wake" is determined. For CRPs, the "effective wake" for each blade row includes the interaction...

... 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...

... performance and pressure pulses have been evaluated for various practical propellers. Finally, the possibility to use PUF3A as a design tool has been investigated. artificial intelligence marine transportation fluid dynamics effective wake fluctuation strength pressure pulse thickness...
