Dynamics study on fractal reaction of oxygen in granular coal
Hong Lin · Meitan xuebao · 2005
Defined the concept of granular coal,and analyzed its structure.Analyzed the migration rule of oxygen in granular coal by fractal geometrical theory.And deduced the fractal dimensions of coal granule and porosity, and the relation of them.The fractal diffusion equation of oxygen in granular coal and the adsorptive velocity equation of oxygen on coal granule fractal surface were obtained on the basis of the concept of fractal probability density.
