Abstract/Summary |
Nowadays, for safety purposes and due to the hazard assessment of industrial processes it is necessary to have a good tool for modelling gas dispersion. CFD modelling has the potential to be an important tool for more reliable prediction of concentration of dangerous species accidentally released into the atmosphere. Thus, also gas dispersion in complex-geometry environments can be solved. Parameters of such model, particularly the turbulent Schmidt number and the surface roughness length as well as their influence on the CFD modelling of gas (Cl2) dispersion, were examined. The results were compared with the experimental data for a small release of chlorine gas. The comparison revealed that the value of turbulent Schmidt number has an essential influence on the concentration prediction reliability and should be much lower compared to the values used in literature in the case of the atmospheric boundary layer. Moreover, it was found that the surface roughness plays a significant role for a realistic prediction of the contaminant concentration.
