【Abstract】 This paper presents a viscous computation method by which the problem of numerical simulation of radiation force and resistance of hybrid monohull is solved and the viscous effect of Hybrid monohull on reducing longitudinal motion is found. The numerical results have a good agreement with the experimental results, which shows that the presented method can be successfully used for predicting viscous effect of the hydrodynamic forces of hybrid monohull and also can improve the precision of the seakeeping performance prediction. Anyway, the present method has important reference values for optimizing the design of hybrid monohull.更多还原
