Z. Z. Hu, D. M. Causon, C. G. Mingham and L. Qian A Cartesian cut cell free surface capturing method for 3D water impact problems International Journal for Numerical Methods in Fluids 71
A 3D Cartesian cut cell mesh generation procedure is developed together with a finite volume Euler solver for a two-fluid system with a free surface. By computing in both the air and water regions simultaneously in a consistent manner, the free surface is automatically captured without the need for any special free surface tracking method. The mathematical formulation including its numerical implementation of the method is reviewed, and results for a number of test cases related to the water entry of a wave energy device are also presented.
