METHOD OF PREDICTING ATMOSPHERIC CONDITIONS IN URBAN STREET CANYON USING COMPUTATIONAL FLUID DYNAMICS IN COMBINATION WITH PHOTOCHEMISTRY

摘要

PURPOSE: An atmosphere environment test method within a street canyon using computational fluid dynamic is provided to accurately simulate an air pollution state of a street canyon by combining v with CFD(Computational Fluid Dynamics). CONSTITUTION: An RANS(Reynolds-Averaged Navier-Stokes equation) is applied in consideration of NOx-Ox-VOC reaction. A GEOS-Chem is a three-dimensional bulb chemical transport model. A wind field is calculated through a CFD model based on an RANS(Reynolds-Averaged Navier-Stokes equation). Transportation about chemical species is numerically interpreted.
