EFFECT OF TURBULENT RETARDATION ON PHYSICOCHEMICAL ABSORPTION.

    Abstract

    Because of the strong coupling beween the mean and fluctuating fields in turbulent flows, the turbulent flux of a passive additive may not respond instantaneously to sudden changes in the mean field. Instead, the flux will be retarded over a space-time domain which affects the mean field. For a statistically stationary passive additive, the effect on the mean field is explicitly spatial. The potential importance of this phenomenon on the enhancement factor for an irreversible, first-order reaction is illustrated theoretically. A comparison with experimental data shows that retardation may be a necessary component of a mechanistic interpretation of physicochemical absorption.
