Numerical modeling of the spread of harmful substances from gas stations

The spread and influence of harmful substances from gas filling stations (gas stations) on nearby buildings, taking into account the aerodynamics of wind flows, is not well investigated. Studying process of the spread of harmful substances in natural conditions causes certain difficulties. Being based on the results of theoretical and experimental studies obtained earlier, the authors performed a numerical modeling of the spread of pollutants emitted from gas stations. As well the authors analyzed influence of these pollutants on nearby buildings taking into account the flowing air flows. The results obtained from numerical modeling make it possible to assess the state of the environment at any point and at any distance from the gas station and allows us to predict the degree of influence of atmospheric air pollution on the environmental safety of residential buildings during the construction of gas stations. Using numerical simulation, it also seems possible to assess the effectiveness of the implementation of planned measures to reduce the negative impact of harmful substances from gas stations.
