Ultrafine particles dispersion modeling in a street canyon: Development and evaluation of a composite lattice Boltzmann model

摘要: Recently, a branch of particulate matter research concerns on ultrafine particles found in the urban environment, which originate, to significant extent, from traffic sources. In street canyons, dispersion affects pedestrian's short term exposure and resident's long as well. The aim present work is development evaluation composite lattice Boltzmann model study particles, canyon microenvironment. proposed has potential penetrate into physics this complex system. order evaluate performance against suitable experimental data, levels have been monitored an hourly basis for period 35 days, canyon, Athens area. results comparative analysis are quite satisfactory. Furthermore, our modeled good agreement with other computational studies. This first attempt air pollutant by application method.
