Venturi effects / microbial wind tunnel

SPATIAL

Squeeze wind through a gap — between buildings, along a passage, under a gable — and it speeds up, carrying and concentrating spores and dust onto whatever lies in its path. This 'microbial wind tunnel' effect explains why certain funnelled spots soil far faster than their neighbours, and why a clean has to target those concentration points.

Venturi Effects describe the acceleration of airflow as it is squeezed through constrictions in a building's geometry — gaps between blocks, passageways, gable channels — creating a 'microbial wind tunnel' that concentrates and drives spores and particulates onto and through specific zones. As a component of architectural aerodynamics, it explains why certain corridors and funnelled elevations carry disproportionate contaminant load and colonisation, and it sharpens the deposition-velocity map of where a property is most at risk.
