The Application of Invariant Modeling to the Calculation of Atmospheric Turbulence

Abstract

A method for the calculation of turbulent shear flows by an invariant modeling closure of the equations for the second-order correlations of fluctuating quantities in a turbulent medium is described. The relationship of the primary computational scale used in this model and the longitudinal integral scale of the turbulence under consideration is determined. With these results in hand, a technique is described by which it should be possible to determine the intensity and integral scale of turbulence measured by instrumented aircraft when only partial spectra are available.
