  Problem Statement: There are two layers of liquid in a glass, air and water respectively. Analyze the mixing between two fluids due to sloshing. Model of Sloshing physics in Ansys Fluent without using any UDF. CFD: Computational Fluid Dynamics (CFD) is the process of mathematically modelling a physical phenomenon involving fluid flow and solving it numerically using the computational process. A CFD software analysis examines fluid flow by its physical properties such as velocity, pressure, temperature, density, and viscosity. Those properties must be considered simultaneously to generate an accurate solution for a physical phenomenon associated with fluid flow.  A mathematical model of the physical case and a numerical method are used in a CFD software tool to analyze the fluid flow. For instance, the Navier-Stokes (N-S) equations are specified as the mathematical model of the physical case. This describes changes in all those physical properties for both fluid flow and heat...
