The Numerical Simulation Of Diffusing Process Of Iron And Steel Industry In The Air

This article simulated on non-steady transport processes of air pollution of iron and steel industry production process, simulated the transport of the air pollution in different wind speed and different obstacle situation, get the consistency field of different situation. Analyzed the concentration field near the ground,pollutant source plane and h=300m plane. Found out the infection of air contamination transport.The main contents and the innovation point of this thesis include as follows:First:Compared with the traditional research method of studying of the air pollution diffuse(The Gaussian mode or revised Gaussian mode that on the specialized topic). The revised onflow flow model has follow traits:the error margin is small,applicability more extensive.Second:Using the method of the numerical simulation on non-steady diffusing process of iron and steel industry in the air and getting the flow field and the consistency field of different time that close to the fact,it's provide for the following works of the topic.Third:By analyzing the numerical simulation result, found out the basic influence factor of air pollution diffuse.So we can reduce the pollution harm to people's health by rational programming.Fourth:The process can widely used to analyzing the pollution exhaust of overhead pollution fountain ; assessing the new estate's air quality; overhead pollution fountion's pollution degree of the localization.
