摘要：

The subject of airflow through large openings includes a large number of different problems, ranging from steady gravitational flows to fluctuating flows due to wind turbulence, and including recirculating flows caused by boundary layer effects in a thermally driven cavity. After a review describing the various physical phenomena, and the existing solutions available in the literature to solve this problem, we present in this paper a general solution to predict airflow through large vertical openings. This solution is able to take into account effects of density gradients and turbulence on gravitational flows, and is compatible with a pressure network description for multizone modelling of airflow in buildings.
