Experimental and Numerical Validation of the Improved Vortex Method Applied to CP745 Marine Propeller Model

The article presents a numerical analysis of the CP745 marine propeller model by means of the improved vortex method and CFD simulations. Both numerical approaches are validated experimentally by comparing with open water characteristics of the propeller. The introduced modification of the vortex me...
