Abstract	Flow and heat transfer at transport of viscous media in industrial systems, pipelines including fields with any configuration of a wall is rather complex task. In given conditions the basic problem in modelling of turbulent effects is connected with necessity of an exact prediction of pulsated dynamic and thermal structures. Modeling of turbulent flow and heat transfer in pipes and channels with use of turbulent model including the transport equations for a component of full tensor of Reynolds stresses and turbulent heat fluxes with basic base from the differential equations for kinetic energy of turbulence and a characteristic time scale of pulsations of velocity field is presented. It is established that the present closing relations for terms of the higher order in the equations of the ginen model and the base are universal enough and rather successful in description of “thin” turbulent processes and mechanisms: diffusion, generation, dissipation, redistribution and convection in complex spatial flows.
