| Abstract: | In this paper a MATLAB program of numerical simulation and visualization of free surface viscous flow based on VOF is presented and the incompressible Navier-Stokes equations in two dimensions are derived by using Finite Difference Method in a uniform Cartesian grid.In order to increase efficiency and to shorten computing time,Parallel Computing Toolbox in MATLAB is used.The numerical simulation for broken dam in two dimensions demonstrates that this program is a reliable and effective numerical approach to... |
