| Abstract: | Dynamical similarity criteria have been provided for modeling of pollutant transport and dispersio'n in neutral environmental wind tunnel,based on turbulent Reynolds number equality-kine matic similar flows are dynamically similar in fully developed turbulent flows.Exact and various approximate simulation approaches used in atmospheric diffusion laboratories for modeling plume rise and dispersion have been summarized.Some recommendations are given. |
