Abstract
A standard method for investigating the air leakiness of a building or component involves the use of fans to generate pressure differences across building cracks. It is often found that the air flow characteristics of such cracks vary depending upon whether the pressure differences are positive or negative with respect to a reference pressure. This note suggests one possible mechanism for explaining these flow differences, based on laboratory measurements using L-shaped cracks.
