Free-surface Simulations Using An Interface-tracking Finite-volume Method With 3D Mesh Movement

Abstract

AbstractIn the numerical solution of a free-surface fluid flow problem, an additional conservation equation (called the space conservation law) has to be solved along with the mass, momentum and energy conservation equations. In this paper a surface adaptive curvilinear finite volume method for solving free-surface flows is presented. The computational mesh defines hexahedra that are used as the control volumes in a finite-volume method in which the mesh moves to adapt to the free-surface. Dependent variables are located at the centre of each volume. Code verification is carried out on a number of inviscid, laminar and turbulent flow cases and the results show good agreement with experimental data and theoretical solutions.
