Abstract
Our present study is a continuity former work on the numerical simulation of an
isothermal jet, turbulent and confined in a cylindrical enclosure. The objective is to
study in an axisymmetric configuration, the performances of models of turbulence
based on the method of the averages of the Navier-Stokes equations (RANS), namely
the model k- based on the concept of turbulent viscosity and the model of the
constraints of Reynolds. Each one is evaluated with two of these versions: Standard and
RNG for k- and LRR and SSG for the RSM.
The validation of the computation results is made for a low intensity of swirl with real
measurements. The commercial computer code Fluent was used as tool
