The combined process of transport and dissolution of microcrystals in a semi-infinite channel is considered. An exact analytical solution of the Fokker–Planck-type equation for the crystal-radius distribution function is found for the case of constant undersaturation. The flux of crystals at a certain channel cross-section, the concentration distribution of crystals, and their dissolution intensity are determined theoretically. We demonstrate that the Péclet number and the coordinate of channel cross-section where the particles are introduced, substantially influence the distribution function and other key characteristics of the process.
