Abstract

In this research article, three (k-ε) turbulence models, (Standard k-ε), (RNG k-ε) and (Realizable k-ε) were compared. The turbulent flow characteristics are illustrated in three-dimensional geometry using the ANSYS FLUENT 18.0 coded turbulence model. Numerical results were verified by comparison with the results of computational fluid dynamics (CFD). Their speed is resolved according to the computational fluid dynamics (CFD) and velocity profiles, turbulent kinetic energy profiles confirmed numerical results. Also, the contour of the flow rate and the vectors shown. One of the most interesting observations of numerical solutions compared to CFD data is that k-ε varieties have a valid estimate of flow properties that are far from wall effects.
