Seminar Abstract:This seminar will present a lattice Boltzmann
method based fracture model which was developed to compute permeability
of coal at the microscopic level. Factors that influence permeability of
coal will also be investigated using this model. Two methods to be
discussed to generate the fracture structure of coal for modelling. For
method one, a multi-parameter random generation-growth method will be
introduced to construct the complex microstructure of coal. The other
method uses non-destructive measurements such as scanning electron
microscopy or micro-computed tomography scanning to describe the
interior structure of coal. With this LBM model the fluid flows in the
coal fracture can be simulated. As a result, the velocity and pressure
distributions of the flow through the pores or fractures in coal rock at
the different stages can be obtained accurately. The simulation results
also provide the numerical information for investigating the
permeability of porous materials, both locally and in the overall, which
could not be measured even by costly experiments otherwise.
