ON THE MODELLING OF EDDY VISCOSITY TENSOR FOR SHEAR TURBULENCE

This paper considers the new eddy viscosity modelling of shear turbulence,where the eddy viscosity is a forth-order tensor.Based on the concept of Moore-Penrose’s generalized inverse matrices,the computational formula is obtained for the components of eddy viscositv tensor. The checking calculation is completed for a plane back-facing step flow. A proposal is offered for application of the eddy viscosity tensor modelling.
