模拟街道峡谷内的流场和污染物浓度的格子玻尔兹曼方法
Lattice Boltzmann method for simulation of air flow and pollutant dispersion in street canyon
摘要
Abstract
A new lattice Boltzmann method model was constituted to simulating the flow patterns and pollutant dispersion in street canyons,and it was applied to simulating the flow patterns and pollutant dispersion of different street canyon aspect ratio(AR=H/W).The results show that it makes more difficult to disperse the pollutants and more concentration near the ground level with increasing the aspect ratio.The numerical results are found to be in better agreement with those of previous studies.关键词
