Abstract

Today, Moving the mass of dust, releasing pollutants and their consequences has become an important issue in Environmental topics and many research and development activities focus on this issue. In the present study, expressed an overview of the status of dust and Environmental problems in the country and described how to model the motion of dust in the range of University of Qom using computational fluid dynamics tools. Then it is said how are atmospheric conditions effect and the deposition of these Particles on the part of the University of Qom numerically. The results showed that the building architecture has a significant effect on the distribution of dust concentration around the building. Then, the effects of wind direction are also studied. The trapped dust Particles will be minimized for a specific angle between the wind and building directions. The effects of temperature gradient (daily and seasonal) on dust concentration are also studied and then the effects of various temperatures on the dust emission studied. It has been observed that considering the temperature variation in computational model leads to reduction of concentration of dust Particles up to %90. Finally, accumulation of settled Particles on the ground level was considered. The results proved the considerable influence of wind direction on accumulation of settled Particles in the central yard of the building.
