Abstract

China has a vast territory of severe cold zones, occupying a quarter of the total land. Heating exhaust from coal heating boilers is an important influence factor of air quality in the winter. This situation will be relieved by some urban planning methods. There is no research about air pollution caused by heating exhaust. In this paper, four governing equations (Continuity equation, Momentum equation, Energy equation and Mass transport equation) are introduced to study contaminant dispersion of heating exhaust. Computational Fluid Dynamics (CFD) is used to compute outdoor wind environment and air pollution condition. In meshing process, a size function is applied to reduce number of grids and improve computational accuracy. Simulation result can achieve influence analysis of air pollution on key elements of urban planning. Study results can provide theory foundation for urban planning.
