چکیده
The issue of coal spontaneous combustion greatly threatens the production safety mining, storage, and transportation. It is significant to study oxygen adsorption understand mechanism combustion. In this paper, based on fractal dimension self-similar geometry, internal pore structure modeled. Then, lattice Boltzmann method employed conduct numerical simulation in coal. Compared with existing experimental data simulation, verified be correct. results indicate that process coal, preferential flow occurs when large pores connect channel. meantime, diffusion coefficient leads an early time for equilibrium. increases increased rate constant. Pore plays a role behavior can provide theoretical support reducing ensuring mine production.

متن کاملLattice Boltzmann Simulation of Polymer-solvent Systems
Received (received date) Revised (revised date) We investigate a new method for simulating polymer-solvent systems which combines a lattice Boltzmann approach for the uid with a continuum molecular dynamics (MD) model for the polymer chain. The two parts are coupled by a friction force which is proportional to the diierence of the monomer velocity and the uid velocity at the monomer's position....
