The Influence of Hydrodynamic Fluctuations on Turbulent Mixing and Chemical Reactions in a Rotating Channel Flow

Turbulent mixing in a rotating channel flow indicates that the transverse transport of a chemically reactive constituent is mitigated by a coupling between the shear component of the Reynolds stress and the longitudinal component of the mean flux of the reactive constituent. In the region of zero intrinsic vorticity, the dispersion coefficient in the cross flow direction is larger than the dispersion coefficient in the spanwise direction. The dispersion coefficient in the longitudinal direction is relatively small.
