Experimental and numerical study of a full scale ventilated enclosure : comparion of four two equations closure turbulence models

For the experiment detailed airflow fields were measured in three cases of ventilation air temperature : an isothermal case, a hot case and a cold case.The experimental data have been used to test four two equations turbulence models. And it appears that none of the models is reliable concerning the cold case whereas they all can predict reasonably the hot and isothermal cases global values of temperature and velocity. Those models are not able to predict the exact experimental velocity and temperature fields.
