Quantitative 3D spatial characterization and flow simulation of coal ...
A 3D digital coal model with macropores (> μm) was constructed by using μCT scanning combined with Avizo image processing, and the equivalent pore network model (PNM) was extracted to calculate the absolute permeability of the coal samples. The CBM flow process in macropores is simulated by COMSOL, and the streamline distribution for the ...
