Computer simulations are used to study mass transfer from a stationary composite cylinder---made of an inner, initially loaded, core and an outer-coating semipermeable shell---subjected to a crossflow. The transition from steady to unsteady laminar flow regime alters the released solute spatial distribution and the mass transfer efficiency (Sherwood number), which is found to depend explicitly on the shell solute permeability. The cylinder internal structure and the initial condition considered…
