Abstract

Reaction-diffusion problems that are characterized by the presence of iso- lated sources along bounding surfaces of a liquid-filled container arise in typical electrochemical applications utilizing arrays of microelectrodes, in modelling corrosion of surfaces, and in models of catalysis. The mathemat- ical treatment of the associated mass transport problem is difficult due to the character of the resulting mixed boundary value problem, whereby reac- tion occurs at isolated sites on boundaries with the remainder of the surface treated as insulating. Here we examine the case of steady-state transport to periodic arrays of circular disc-shaped microelectrodes mounted flush in an infinite, insulating planar boundary.
