摘要
In double-layer stratified turbulent flow, the deviation function of the concentration from the cross-section mean and the dispersion coefficients are studied. The one-dimensional simplified dispersion equation is extended to double-layer turbulent flow. The velocity distribution in the upper flow region is logarithmic, and in the lower region is of the power-law. The paper gives particular forms of the concentration deviation functions and accurate formulae of longitudinal dispersion coefficients.
