Abstract

The numerical simulation of flow around the pile acted by the internal cnoidal waves has been made by building two-dimensional numerical wave flume based on FLUENT software. Internal cnoidal waves are generated by push-pedal method and the free surface is captured by VOF method. The wave shapes with different amplitudes and different periods are obtained. Moreover, the force of the internal cnoidal wave with specific period and amplitude on different kinds of piles in three-dimension are simulated. The trend of inertial force and the viscous force on the piles is analyzed and the total wave forces on piles with different shape are compared.
