Buoyancy effects on cross-ventilation

ORAL

Abstract

Wind-driven cross-ventilation occurs when there are openings on opposite walls of a room, at equal height. This talk will present the results of laboratory experiments using a water flume and a cross-ventilated model room at 1/10th scale. These experiments examine the effect of an initial indoor-outdoor temperature difference on the ventilation rate and the removal of contaminants from a cross-ventilated room. We present simple mathematical models that explain the observed ventilation rates.
