| Abstract: | High building density, narrow streets, small open spaces and above all large population in a urban environment present a special challenge and urgency for modelling tools with which dynamic and quantitative prediction could made possible. This paper reviews the modelling studies on gas dispersion modelling with a special focus at micro scale modelling and modelling methodology. It proposes a semi - dynamic modelling approach that solves firstly a steady flow field and then dynamic dispersion modelling. |
| Keywords: | toxic gas leakage dispersion model computer model |
