A study of a probalistic model of wind induced ventilation.

There are several reports on studies of wind tunnel experiments and calculations on the response of air flow at an opening against the periodic variation of wind velocity and pressure. In these studies, the fluctuating components of natural wind velocity have been treated definitely. In this paper, theoretically derives the probability density function from a probabilistic model of wind velocity around the buildings, the consequent wind pressure, and the resulting ventilation rate and contamination concentration. Validates results using a model of an enclosure exposed to wind, with a nozzle as the inlet and an orifice as the outlet.
