Turbulence Models and the Synthesis of Random Fields for Acoustic Wave Propagation Calculations

A comprehensive set of equations is derived for correlations and spectra of atmospheric turbulence, useful for wave propagation calculations and other applications. Three basic turbulence models are considered: (1) the Gaussian, (2) von Karman, and (3) Kolmogorov models. Two extended forms of the von Karman model are also described: the Mann model for a shear driven atmospheric surface layer, and the Hunt/Graham/Wilson model for a convective boundary layer. A new method for synthesizing random fields from an inhomogeneous spectral model, called the generalized random phase method, is described and applied to the various turbulence models.Army Research Lab Adelphi is the author of 'Turbulence Models and the Synthesis of Random Fields for Acoustic Wave Propagation Calculations' with ISBN 9781423558934 and ISBN 1423558936.
