description of dense-gas dispersion, and distinguish it from the dispersion of neutrally or positively buoyant gases, are the tendency of the gas to spread out along the ground as a density current and the reduced capacity, due to the stable density stratification at the cloud interface, of ambient turbulence to mix the gas with the.

releases of dense (i.e. denser-than-air) gases. The methods for estimating dis­ persion of pollutants (which are generally neutrally or positively buoyartt in their behaviour) are not applicable.

The absence of workbook methods has been due to the rapid development of the subject of dense gas dispersion over the past ten years or so.

Particular features of dense gas dispersion are discussed and compared with the dispersion of neutrally buoyant gases.

Methods for incorporation of topographical and obstruction effects are also discussed, together with a range of mathematical models available for the prediction of dense gas by: Finally, a proper dispersion model must be selected to describe the denser than air gas dispersion.

From these models the downwind concentration, duration and other parameters may be calculated. Thus, looking to provide Bogotá D. with a fully functional computer tool, two dispersion models were programmed as well as seven source models. Gas Dispersion COMPETENCE IN GAS DETECTION STL Learning from history Recognising that accidents do happen, If the density of a gas is neutral with air, then this gas will move with air and be pushed and pulled by air currents.
