Numerical calculation of dust and smoke transport on complex topography

Abstract

The paper presents a three-dimensional model for computation of dust and smoke transport in the air. Flow-field was solved from continuum, momentum with statistic assumption. Dust and smoke are calculated by solving their transport equations. The equations are solved in “sigma” transformed coordinate by finite volume method with ADI scheme of Douglas - Gunn. The ground effect was modeled. The model was tested over analytical solution. Some preliminary results of simulation for dust and smoke transport in Vung-Tau city are also presented.
