The fluid mechanics of natural ventilation--displacement ventilation by buoyancy-driven flows assisted by wind

摘要

This paper describes the fluid mechanics of natural ventilation by the combined effects of buoyancy and wind. Attention is rstricted to transient draining flows in a space containing buoyant fluid, when the wind and buoyancy forces reinforce one another. The flows have been studied theoretically and the results compared with small-scale laboratory experiments. Connections between the enclosure and the surrounding fluic are with high-level and low-level openings on both windward and leeward faces.
