Computational analysis of wind driven natural ventilation in buildings

For that study, a RANS equation approach is applied to wind driven natural ventilation in a cubic building. Two different models are considered. The velocity and pressure distribution inside and around the building are determined along with the ventilation rate for three different configurations : cross-ventilation, single-sided ventilation with an opening on the windward wall and single-sided ventilation with an opening on the leeward wall.. The numerical results compared with the experimental data show a good agreement.
