The diffusion of a passive scalar in turbulent shear flows is studied from thestatistical viewpoint. The scalar flux, the scalar variance, and the squared-scalarflux, which characterize the diffusion processes, are calculated from the two-scaleDirect-Interaction formalism. An equation for the time evolution of the scalarvariance at high Reynolds and P<6cIet numbers is shown to be written by usingthe mean scalar and two statistical quantities, such as the turbulent energy and theenergy dissipation rate of the velocity field.
