Abstract

Understanding dissolution kinetics of a colloidal particle in an aqueous solution is of great importance in many pharmaceutical and biochemical applications. This thesis presents theoretical analysis of low Reynolds number flow dynamics and mass transfer of a dissolving spherical particle in a unidirectional oscillatory flow field. The coupling of fluid flow and passive motion of the particle are resolved analytically, and the transient mass transfer associated with the oscillation of the particle is numerically computed. The flow patterns, mass transport, and the simplified long-time dissolution process under various saturation concentrations and flow conditions are discussed.
