Numerical Analysis of 2-dimensional Fluid Flow with Free Surface using VOF technique

A computer code for analyzing 2-dimensional fluid flow with free surface has been developed. The main features of this computer code are (1) the modifica-tion of a VOF technique with improved numerical accuracy of stress boundary condition and the mass conservation law on free surface, and (2) the introduce of a k-e model in which an attenuating behavior of turbulent intensity near free surface can be expressed.The results of verification show that the numerical solutions agree well with the experimental data for free surface shape and velocity profiles.
