Abstract

Constant-density, isothermal planar mixing layers with and without chemical reaction are studied. A series of problems involving an isolated vortex, a row of stable vortices, and an unstable vortex sheet are examined to understand the effects of coherent vortical structures on the mixing process. Diffusion is superimposed on the stretching and winding of the material lines. Probability density functions are calculated from the concentration profiles. Scalar dissipation rates are found to depend strongly on the vortex Reynolds number and weakly on the Schmidt number. Volumetric mixing rates are predicted to be identical on the high-speed and low-speed sides of a mixing layer.
