At last the mathematics model of leachate diffusion have established according to hydromechanics, the formula of pollution diffusion and the research of result of other researchers, Finally calculation has been conducted to test the established model by some date.
The mass concentration of CO and NO x in Zhongshanlu were related with vehicle flow, almost was direct proportion, the peak flow were in the time of 10, 14 and 18. Its environmental capacity analysis was made according to the concentration of CO and NO x with the model of pollution diffusion, the simulative result was similar to the real determination
This paper adopts FLUENT software,by virtue of advantage of simulate actual circumstances and particular data,We used FLUENT software to process numerical simulative copy of the pollution diffusion whether the ambient residential area in the circumstance of southeaster will affect air pollution diffusion of the operation infilling in refuse dump.
The motor vehicle emission pollutants diffusion mode is developed for crossroad and T-intersection in urban street on the base of OSPM mode and Nichoson box mode developed by Beijing Polytechnic University.
A simulation test was conducted for an urban air pollution model under special conditions through wind tunnel experiment,on the basis of theoretical analysis,combining specific situations of an urban air pollution. Mathematical and physical models of urban air pollutants diffusion suitable for certain conditions were also set up, based on which the test data were analyzed and processed,and a general rule of an urban air pollution under special conditions was also obtained,which can be used for estimating the diffusion concentration of urban air pollutants.
Considering the environmental current status and discharge intensity of atmospheric pollutants in Guilin power plant “substitution of small power plant with a bigger one” technical renovation project, combining relative guides and specifications, Gauss's mode is adopted in this paper to calculate the ground concentration of atmospheric pollutants diffusion in the overhead creel points sources, and its effect on the environment is analyzed
The diffusion of contaminant from immobile liquid within the pores of the fractured rock into the mobile liquid in the interstices is handled by means of a time constant the estimation of which is described.
With this in view, an experimental methodology to monitor diffusion of contaminant(s) through the intact and fractured rock mass, with the help of a USDTS (Ultra-Sensitive Devices and Technical Services) conductivity meter, has been developed.
