多孔質層透過流れにおけるスカラー輸送場のLBM解析

抄録

Porous filters are widely used as a means of removing harmful substances in the atmosphere or water. They realize the required functions by trapping and depositing harmful substances contained in the fluid inside or on the porous substrate. We developed a numerical simulation technique on the scalar transport field in the permeate flow of the porous layer using Lattice Boltzmann Method (LBM). Spatial variation of porosity and thermofluid propreties in porous layers were taken into account in the developed LBM model. A LBM simulation by the developed model on a permeate flow with chemical speies and heat transfer showed a good agreement with those calculated by finite element method (FEM).
