A Method to Calculate Resistance of Ship Taking the Effect of Dynamic Sinkage & Trim and Viscosity of Fluid
A method is presented to calculate the resistance of a ship taking the effect of sinkage &trim and viscosity of fluid.The free surface flow field is evaluated by solving RANS equations with VOF method.The sinkage and trim are computed by hydrodynamic equilibrium equations.The method can be divided into direct and indirect method according to the way to calculate trim of ship.The software Fluent is used to implement this method.With dynamic mesh being used,the position of a ship is updated by the motion of ship + boundary layer grid zone.The present methods have been applied to the INSEAN2340 hull for different Froude numbers and are found to be efficient for evaluating the flow field,resistance,sinkage and trim.
