Modeling of the turbulence transporting of admixture over a heated surface
The paper contains a model of shear turbulent flow closure based on the second moment equations for velocity, temperature and concentration fields. The model is constructed on approximation of local - equilibrium turbulence. The solution of the obtained equation is represented in two factors, the first one describes homogeneous flow and the second takes into account the influence of Archimedes' forces, which depend on Richardson's numbers. The minimal number of empirical constants taken from theories of homogeneous turbulence is applied in the model.
