THE SECOND-ORDER MODEL OF TURBULENT HEAT AND MASS TRANSFER: MODELLING OF THE SCALAR FIELD HOMOGENEOUS TURBULENCE
Résumé
Based on the 2nd-order model suggested in (Kolovandin 1990) numerical modelling of the nearly homogeneous turbulence of the velocity and transported passive scalar fields is considered. The work is aimed at a detailed study of the effect exerted by the basic factors of turbulence generation - the gradients of the averaged velocity and scalar values - on the evolution in time of the statistical characteristics of turbulence which, whithin the framework of the 2nd-order model, determine the processes of turbulent momentum and heat transfer at arbitrary turbulent Reynolds and Peclet number.
