Abstract This report presents the results of a study to develop a numerical model to accurately calculate the trajectories and concentrations of reactive pollutants emitted from localized sources. The numerical model employs the solution of the full three-dimensional Navier-Stokes equations along with the solution of the species density equation by summing over Lagrangian mass points. The mass points are transported by the mean wind field and moved with a random walk technique that simulates the turbulent diffusion. The effect of chemical reactions are modeled by reweighing the Lagrangian mass points. The equations are solved for regions of space where terrain features or buildings may cause strong distortions in the flow field. The numerical techniques are verified by comparisons with analytic formulas, including the boundary layer above a plate and the Gaussian plume. The method was used to calculate photochemically reacting plumes using a simplified inorganic photochemical reaction model. Portions of this document are not fully legible.
