| Abstract: | The prediction of propulsion factors of propelled ship model is an integrative problem that involves calculations on ship-propeller and air-water two phases viscous flow field.Based on the analysis of the influence of the wave making on the propulsion factors,a simplification numerical model to calculate the propulsion factors of self-propulsion ship model is presented,in which the wave making simulation is separated form the calculation on the flow field of the propelled ship model.The numerical methods fo... |
