CFD Analysis of the Influence of Meteorological Conditions on Motion of Ammonia

Popis výsledku v původním jazyce

The article presents the results of a numerical CFD model of gas ammonia plume motion and dispersion after an accidental release from a real ice stadium situated in an urban area. The CFD analysis was performed using the ANSYS Fluent 14.0 for two seasonsand eight wind directions. Sixteen tasks emerged, the results of which can define the influence of meteorological conditions (wind direction, wind speed, temperature, etc.) and surrounding buildings on the motion and dispersion of pollutant plume. The simulation was performed with real local meteorological data. The numerical model had been verified by tasks performed in a low-speed wind tunnel. The results show that the influence of meteorological conditions, especially the influence of calendar seasons, on the pollutant plume propagation can be very pronounced. Principles and conclusions drawn from this and similar analyses may have great benefits for emergency planning in complex urban areas.
