Numerical simulation on application of diffuse regulation with power dust in transshipping site

The present article is aimed at introducing the authors' numerical simulation on how to solve the problem of power dust pollution on the transshipping site. In our research, we have applied the numerical simulation to the calculating practice of the diffuse situation and movement track of the granules in a small controlled roomage. At the same time, the movement track of the power dust can be demonstrated on a computer screen in a virtual reality form with the up-to-date calculating techniques. Since the air current on the transshipment site is usually in a rapid torrent form, it is hard to catch the diffuse regulation simultaneously. Therefore, it makes the researcher nothing to do but to establish a movement equation of particles to analyze the stress condition of the single dust pellet on the basis of simulation. By using Lagrange equation to trace the track of the diffusing, the equation of granule diffuse can finally be obtained on the computer through the virtual reality and programmes such as Visual Basic and Visual C++. The practical application of the simulation proves it of practical value in dealing with the power dust on the transshipment site.
