Abstract

MIXING PROCESS IS ONE OF THE MOST IMPORTANT PHENOMENA IN ENGINEERING SCIENCE. TURBULENT EFFECT AND OSCILLATIONS IN THE BASE FLOW INCREASE THE MIXING RATE NOTICEABLY. IN THIS RESEARCH A NON-REACTING CONCENTRATION FIELD IN A MIXING LAYER IS SIMULATED FOR HIGH REYNOLDS NUMBER BY SOLVING THE SCALAR TRANSPORT EQUATIONS. WE USED A GRID FREE CFD SCHEME NAMED TRANSPORT ELEMENT METHOD IN ORDER TO MODEL THE CONCENTRATION FIELD IN A LAGRANGIAN FRAME. THE CONCENTRATION GRADIENT IS CALCULATED IN VORTEX STRUCTURES AND OTHER CROSS SECTIONS IN THE FIELD. ALSO MEAN CONCENTRATION PROFILE AND CONCENTRATION FLUCTUATION DIAGRAM ARE OBTAINED FOR VARIOUS DIFFUSION COEFFICIENTS. THE RESULTS ARE IN GOOD AGREEMENT WITH OTHER EXPERIMENTAL DATA.
