Special Features of Dispersed Material Dissolution Process in Shear Flow of a Viscous Liquid

Resumo

A theoretical study is made of the solid dispersed materials dissolution process in shear flow of a viscous liquid. A sphere-in-cell model that takes account of the effect of the solid disperse phase concentration on the conditions of mass transfer on the surface of a random particle is analyzed. Analytical equations for calculating the shear stress and Sherwood number averaged over the surface of the particles in a shear flow are derived. The basic mechanisms of shear flow of a viscous liquid around spherical particles are disclosed.
