Abstract
In this article, different impinging jet configurations are studied by means of time-averaged Navier-Stokes simulations. In this technique, explicit algebraic Reynolds stress models and both nonlinear and linear eddy–viscosity models are explored jointly with k − ∊ and k − ω platforms. The main object of this work is to study numerical performance and accuracy of models when they are used in the simulation of both plane and round impinging jets. With this purpose, results from numerical simulations, using different models, are compared among them and with experimental data available in the literature. Comparisons are performed in terms of mean and fluctuating velocities and global parameters, i.e., the local Nusselt number. A verification procedure is applied in order to ensure the credibility of the numerical solutions.
