Numerical Investigations of Waves Interacting with Free Rolling Body by Modified MPS Method

In this paper, interaction between regular waves and free roll motion of a two-dimensional (2D) floating body is investigated by our in-house meshless particle solver MLParticle-SJTU based on modified moving particle semi-implicit (MPS) method. Numerical wave tank (NWT) is developed to calculate the interaction between waves and floating body, including wave-maker module and free roll motion module. The comparison between the numerical wave elevation and analytical solution shows that the MLParticle-SJTU solver can provide acceptable accuracy of wave making. Roll motion and force acting on the floating body in waves are in good agreement with experimental results. Profiles of the wave surface surrounding floating body are presented.
