Invariant modelling turbulent currents of reactive gases

The modern approach is surveyed to invariant simulating of developed turbulent flow of multicomponent reactive gases, with reference to specificity of simulating of shift streams. The basic attention is given to a problem of an intercoupling of a chemical kinetics and turbulent transfer, and also development of a semiempirical computational method of coefficients of a turbulent interchanging in the stratified mediums, founded on usage of the nonstationar equations of transfer for the second correlation moments pulsatory of thermo-hydrodynamic parameters.
