Exponentially Expanded Grid Network Approach (EEGNA): An Efficient Way for the Simulation of Electrochemical Problems at Spherical, Cylindrical and Rotating-disk Electrodes

Abstract

An exponentially expanded space grid technique has been employed in the network simulation of chronoamperometric and voltammetric problems in spherical, cylindrical and rotating-disk electrode systems, leading to an effective simulation strategy for electrochemical problems: exponentially expanded grid network approach (EEGNA). The success of this method is largely due to the improved ability in processing the boundary singularities existing for non-planar diffusions and the enhanced simulation speed and accuracy in contrast to the uniform or quasi-uniform grid network approach.
