Modification of method of invariant modelling of Donaldson for turbulent shear flows of reacting gas mixes

Generalization of Donaldson’s invariant modelling method on the developed turbulent flows of chemically active gas medium with variable density and variable thermal physic properties is given. Procedure of averaging of speeds of chemical reactions any order is offered, the differential transport equations for the second correlation moments of turbulent pulsations of velocity, temperature and concentration of mix components are deduced, the scheme of semiempirical modelling of correlations of the high order entering into these equations is planned. The special attention is given to a problem of interference of chemical kinetics and processes of turbulent heat-and mass transfer, and also working out of semiempirical method of the turbulent exchange factors (tensors) calculation based on use of locally equilibrium approach for transport equations of second correlation moments.
