The methodologies used in the CFD analysis rely on a simple procedure as outlined below. The physical boundaries of the problems are defined; then the volume as occupied by the fluids divided to form either uniform or non uniform mesh. After that, physical modeling is defined through the equation of species conservation, radiations, motions and enthalpy. The behavior and characteristics of the fluids are then defined at the peripheries of the problem and simulation commences as the equations are done repeatedly. The final stage in the CFD analysis is where a post processor is used to for analyzing and visualizing the results.
