Abstract
The paper presents and discusses internal pressure and discharge coefficients for a building with wind-driven cross-ventilation caused by sliding window openings on two adjacent walls. The study found that both coefficients vary considerably with the opening area (porosity of wall(s)) and the inlet to outlet ratio. Comparisons with previous work were also carried out. Experimental results verify the unsteady pressure and velocity field, particularly in the case of cross-ventilation with large opening areas. For such cases, a simulation sensitivity analysis of wind-induced building ventilation confirms that airflow rates vary considerably when different discharge coefficient values are used.
