Water is contained between two infinite parallel plates separated by a small distance h. The bottom plate is stationary and the top is moved at a constant velocity U so that a simple, parallel shear flow is generated. A dilute plug of solute wi th a diffusivity D is placed in the channel. Neglecting the effects of diffusion in the x - direction, find the effective dispersion coefficient for this problem
