The report details the progress made at A.R.A.P. during fiscal year 1975 towards the goal of developing a viable computer model based on second-order closures of the turbulent correlation equations for predicting the fate of nonchemically reacting contaminants released in the atmospheric boundary layer. The invariant turbulent model discussed in previous reports has been further verified by new comparisons between model predictions and experimental observations. Model capability has been extended by increasing the dimensions of the program to permit the calculation of two-dimensional, unsteady turbulent flow. A number of practical plume calculations were made and compared with standard Gaussian plume assumptions.
