Abstract

Building ventilation is affected not only by the steady mean effect of air pressures and temperatures around and within the building, but also by the turbulent nature of wind causing a diffusion of air through openings and cracks in the building envelope. The ventilation of an enclosure with a single opening subjected to a turbulent impinging airstream is studied and simple theoretical models are derived to assist in understanding the physical phenomena causing airflow through the opening. These are compared with the results of experiments on a large scale model. The need for further work on this problem is stated.
