As a part of this effort,three mathematical models were developed. The Reactive Plume Model (RPF),adopting a trajectory approach,accommodates variations in wind speed,plume spread,and ambient concentrations. A kinetic mechanism was used to describe gas-phase reactions between NOx,SOx,and hydrocarbons. The Buoyant Plume Model (BPM) predicts plume rise and effluent dispersion near the stack. It invokes the Navier-Stokes equation with the Boussinesq approximation,and allows for plume-generated turbulent diffusion. The Plume Dispersion Model (PDM) simulates pollutant distributions far downwind,PDM solves the three-dimensional atmospheric diffusion equation,and incorporates variations in wind speeds. 收起
