... Abstract Rayleigh damping is introduced into a potential flow based method in order to improve wave resistance determination. The problem is modelled using Kelvin sources with a translating speed. A dissipative 3D Green function is applied. The inclusion of Rayleigh damping removes...

... equations with a mixture of fluid technique and a free surface capturing method to resolve for non-linear free surface effects. The proposed method overcomes the approximation introduced by empirical corrections factors in potential flow based solvers, allowing for accurate prediction on the real shape...

... of marine 3-D hydrofoils. A boundary element panel method is used to solve the potential flow past a typical ship rudder, and obtain the forces acting on it. Investigations are carried out on the optimal settings, in order to tailor the method for this type of analysis. A comparison of the results is done...

.... This paper will deal only with wave effects. Wave induced loads on the floater are essentially a potential flow effect, while loads on mooring and risers have a major viscous fluid contribution due to combined current and wave loads. However, damping of wave induced floater response in certain modes...

... damping was introduced by shifting the collocation points upstream of the sources. In the case of the continuous representation of the potential, boundary conditions were imposed upstream of the submerged singularities. INTRODUCTION The potential flow around a hull with constant forward velocity...

... ABSTRACT: This paper refers to the Rankine source technique to predict the potential flow around an oscillating hull with constant mean forward velocity, focusing on the type of linearization adopted for the free-surface condition. Double-body and Neumann-Kelvin linearized free-surface...
