摘要：
This paper derives some new analytical solutions for buoyancy-driven natural ventilation in buildings with three openings. The new solutions are used to analyze the effect of the middle opening height and area on the natural ventilation performance. The criteria for flow direction switching for the middle opening is established. It is also proved that the neutral plane level in the three-opening buildings depends only on geometrical parameters. Natural ventilation of buildings with two openings affecting by supply- or exhaust-only mechanical systems are also investigated analytically. These new analytical solutions can also be used for testing Bernoulli equation-based numerical method.
