This paper presents the numerical simulation of unit step free overfall. Two-phase flows model is applied for this study with the basis of volume of fluid (VOF).
Least-squares finite element method is used for solving the unified Navier-Stokes equations which governs both the fluid and gas phase. For trading the interface of two difference phase, fixed mesh (front tracking) simulation is coupled with the additional colour function. The simulation results are compared with the experimental data and other computational solutions, it shows very good agreement between each other. LSFEM provides a very good tool for simulating the flows with free surface.
