Modelling of water flow on small vessel’s deck
Green water moving on deck of small vessels affects their motion and can contribute to the vessel capsizing. The phenomenon is nonlinear and its description using mathematical differential problems remains to be difficult. This paper presents a numerical model, based on shallow water flow, describing water flow on moving ship’s deck. Up to now simplified methods have been applied to determine ship motion in irregular waves.
The shallow water method is developed to include it into ship motion equations. The paper presents verification of this method and the results of the simulation of water moving on small vessel’s deck.
