Abstract

Dispersion of non-buoyant and dense gas emitted out of a ground level source was studied in a boundary layer wind tunnel. Concentration of gas was measured on a simple rectangular building model using suction taps and a flame ionisation detector. Influence of windward or leeward orientation of the facade with suction taps as well as influence of velocity above the boundary layer was studied. Results have proved significant differences of gas concentration on the windward and leeward side, also differences in concentration according to height above the tunnel floor were observed. Keywords: gas dispersion, boundary layer wind tunnel, rectangular building model, flame ionisation detector.

Keywords
