The turbulent flow pattern is calculated with a low Re number version of the k-∈ model in a room with two-dimensional isothermal flow.
The results are compared both to LDA measurements obtained in a scale model and to other data obtained by numerical simulation.
The overall performance is good and indeed satisfactory. With respect to maximum velocity and turbulence level in the occupied zone the results are very good and with respect to the decay of the maximum velocity in the wall jet and the growth of jet width small discrepancies are found.
