Abstract

In this work different impinging jet configurations are studied by means of time averaged Navier-Stokes simulations (RANS). Within this technique, Explicit Algebraic Reynolds Stress Models and both Non-linear and Linear Eddy Viscosity Models are explored jointly with κ − ε and κ − ω platforms. The main object of this work is to study the numerical performance of models when they are used in the simulation of both plane and round impinging jets. With this purpose, results from simulations are compared among them and with experimental data available in the literature. A verification procedure is applied to ensure the credibility of the numerical solutions.
