Numerical prediction of three-dimensional highly-turbulent flow with free surfaces
To predict complicated three-dimensional flow, a modified \(K\)-\(\varepsilon\) turbulence model is derived. The governing equations of turbulent flow over irregular boundary are developed by analyzing the solid-liquid two-phase flow model. A partial cell parameter is introduced to treat irregular boundary. The formulation allows curved boundaries and internal obstacles or islands. A simple method is described that is based on the concept of a fractional volume of fluid.
