SOFC多孔阳极内微尺度流动的Lattice-Boltzmann模拟
Lattice-Boltzmann simulation of micro-scale flow in porous anode of SOFC
摘要
Abstract
in order to simulate the micro-scale flow in porous anode of anode-supported solid oxide fuel cell, a multi-component gas flow model was built through Lattice-Boltzmann method and the porous media was reconstructed by numerical technique. Based on the validation of micro-scale flow model of complex porous media, the effect of microstructure and fuel component on mass transport and concentration polarization was analyzed. Conclusions are drawn out: Lattice-Boltzmann method is competent for the simulation of micro-scale flow in porous electrode, and the concentration polarization of SOFC anode is highly related to fuel component, current density and anode microstructure.关键词
