Abstract

Experimental investigation of dispersion from ground source on a single building model was performed. The measurements were conducted in boundary layer wind tunnel in Aerospace Research and Test Establishment (VZLU). Simple rectangular building model, gas flow controllers and flame ionization detectors were used for these experiments. Emissions presented non-buoyant and heavy gases emitted out of a ground-level point source. Tracing gas (ethane) was used for the concentration measurements. Effect of changing source concentration and source distance was studied both on windward and leeward side of the model building. Significant differences between these two basic cases were observed.
