Abstract

In this paper three-dimension turbulent buoyant cases of heat transfer and air flow has been presented for enclosed cooling space. Experimental study is carried out to validate the numerical simulations, and the predictions are performed by means of the Realizable k-? and SST k-? models by performing simulations on FLUENT 6. 3. 26. Comparisons between the predictive results and the experimental data reveal that both of the tested turbulence models are capable of capturing the main qualitative flow features satisfactorily. The airflow in a room ventilated by displacement diffuser, slot diffuser, square diffuser, and grille diffuser is calculated by the simplified system, respectively. Comparing calculated results to measured data, it is clear that the simplified methodology can predict indoor airflow and temperature gradient with satisfactory results for engineering applications.
