Abstract

An adaptive mathematical model was developed to determine the local phenomenological properties of turbulence in two phase solid particles-gas system. Equations for predicting the dependence of the eddy viscosity and mixing length on the dimensionless radial position in the pipe were obtained. The proposed equations have been tested using own experimental measured data as well as data available in literature devoted to Newtonian turbulent system. Distributions of eddy viscosity and mixing length over the cross-section are given. In deriving the set of equations for the calculation of eddy viscosity and mixing length we assumed the non-Newtonian character of the turbulent two phase solid particles-gas flow.
