Development of Accurate Interface-Capturing method for Free Surface Flow Analysis based on CIVA/VOF method

This paper presents an accurate interface-capturing method based on CIVA/VOF method for the analysis of free surface flows. The incompressible Navier-Stokes equation and the advection equation is employed for the basic equations. The stabilized FEM based on the SUPG/PSPG method is employed in order to solve the velocity and the pressure. The CIVA method is employed to solve the position of the interface accurately. A new volume correction method is also presented. The present method is applied to the two dimensional broken-dam problem and three dimensional sloshing problem. The computed results show the validity and efficiency of the present method.
