Modelling of Shearing Turbulent Motion in the Upper Atmospheres of Planets.
Abstract:
The modern approach to invariant modeling of developed turbulent flow of multicomponent reactive gases, with reference to specificity of simulating of shearing currents in the upper atmospheres of planets considered. The basic attention is given to a problem of an intercoupling of chemical kinetics and turbulent transfer, and also development of a semiempirical computational method of coefficients of a turbulent exchange in the stratified mediums grounded on usage of the evolutionary equations of transfer for the second correlation moments of pulsatory thermohydrodynamical parameters. The procedure of definition of exterior scale of turbulence is offered permitting in an interactive mode and self-consistent with a motion of medium, to calculate coefficients of a turbulent exchange under the known structural performance of an index of refraction of air, defined in turn under the data of atmospheric sounding by light from a star.
