Description of Turbulent Flows Using a Kinetic Model

A closed system of equations for describing turbulent flows is obtained. Additional equations for the cross pulsation moments are derived using a balanced kinetic equation, which was previously used to obtain a quasi-gasdynamic system of equations. Numerical results for the problem of a two-dimensio...

Description
Summary:A closed system of equations for describing turbulent flows is obtained. Additional equations for the cross pulsation moments are derived using a balanced kinetic equation, which was previously used to obtain a quasi-gasdynamic system of equations. Numerical results for the problem of a two-dimensional mixing layer between two flows are presented.
