Weil, J C

A three-part study was conducted to improve the basis for predicting stack plume dispersion in complex terrain. The study involved developing a mathematical model for a buoyant plume in neutral and stably-stratified flows over a two-dimensional hill, testing the model with wind tunnel experiments under idealized conditions, and comparing field measurements with wind tunnel simulations of stack plume dispersion from a 'real' source in complex terrain. The mathematical model consisted of equations describing the ambient wind field and equations describing the plume superimposed on the wind. The equations were solved numerically to obtain the plume characteristics. A 1:2000 scale wind tunnel model of the stacks and terrain at the Westvaco pulp mill (Luke, MD) was built to simulate the transport and dispersion of stack SO2 plumes about a large nearby hill.
