Numerical modeling of buoyant plumes in a turbulent, stratified atmosphere
Abstract A model for bent-over plumes in atmospheres having complicated vertical structure is presented. It uses a mixed Eulerian-Lagrangian or parabolic modeling treatment in which a computational mesh oriented vertically and crosswind translates downwind at the local windspeed. Knowledge of atmospheric vertical profiles of windspeed, virtual potential temperature, relative humidity, turbulence kinetic energy and turbulent viscosity are required in a problem specification. The model is used successfully in simulation of plume rise and spreading in both stable and neutral atmospheres and of smoke plume transport in an atmosphere which is stably stratified below 400m and neutrally stable at higher elevations.
