Abstract

The irreversible loss of chemically active solutes by reactions at the boundary and the reversible adsorption on the flow boundary have been observed experimentally. Removal of solutes at the boundary alone reduces the rate of longitudinal shear dispersion; in contrast, the retention of solutes in the region close to the flow boundary alone increases the rate of longitudinal shear dispersion. Expressions are derived for the longitudinal shear dispersion coefficient and skewness. The results are applied to the practical example of a chemical flow reactor to quantify the effect of flow boundary retention when there exists reaction at the pipe wall. (from Author)
