... This paper presents computational techniques to predict the fully unsteady interaction of two hydrofoils (rotor and stator) and to calculate the unsteady trailing wake geometry in the case of a propeller. A boundary element method is developed to simulate the unsteady performance of moving...

... This paper presents results from the application of the genetic algorithm (GA) technique to the design optimization of hydrofoil and marine propeller incorporating the potential-based boundary element method (BEM). Although larger population size as implemented by simple genetic algorithm (SGA...

... analysis of such scale effects is based on a combination of two- and three-dimensional hydroelastic models utilizing potential flow theory with an implicit account of viscous effects. scale effect formula hydrofoil cavity length oscillation lift oscillation cavitation number upstream cavity...

... The flow of a propeller inside of a tunnel is addressed. A numerical method is developed in which the flow inside the tunnel is treated via a potential-based panel method. First, the method is applied to the two-dimensional flow of a hydrofoil inside of a tunnel. The total and the perturbation...

... for hydrofoils and propellers. A consistency test is imposed by applying this linear relationship to compare the results of the panel method and a lifting surface method. Finally, the improved propeller panel method is tested for convergence, and compared to other methods. thickness hyperboloidal panel...

... problem the use of a full scale test object is advantageous. Accordingly, the idea of using a hydrofoil corresponding to the outer part of a full scale propeller blade was adopted. The hydrofoil was tested in the high speed test section of the SSPA Cavitation Tunnel. By varying the water speed over...
