Description:
A viable computer model was developed that is based on second-order closure of the turbulent correlation equations for predicting the fate of nonchemically reacting contaminants released in the atmospheric boundary layer. The invariant turbulence model discussed in previous reports has been extended to compute the development of buoyant plumes. Numerical program capability has been extended by improving the speed and accuracy of the two-dimensional unsteady turbulent flow calculation. Plume calculations are made for buoyant plumes rising into a stable quiescent atmosphere and stable, neutral, and unstable moving atmospheres. An examination of the application of an integral approach to our turbulent boundary layer model is also included.
