CFD simulation of gas pollutant motion and dispersion problem in wind tunnel with respect to Froude number

Popis výsledku v původním jazyce

Low speed wind tunnels have been used for simulation of wide range of physical problems. One of many possible applications is a simulation of gas pollutant motion and dispersion considering different density of each one. Source term can be defined as a point source, line source or volume source. If modeled geometry with the source is downscaled geometrically and pollutant release is limited (considering all other atmospheric conditions consistent), the plume of pollutant can change its way of motion anddispersion. These changes include not only a shape of the plume but also an ability of plume to climb or descent in the atmosphere. Especially plume vertical motions are of the highest importance for the plume motion and dispersion in the real atmosphere. The main point of this article is to prove that downscaled physical experiments based on gas pollutant?s motion and dispersion could not be always the best approach for making gas dispersion studies in the field of emergency planning).
