SIMULATION OF MICRODISC PROBLEM IN SPHERICAL CO-ORDINATES. APPLICATION TO ELECTROCHEMILUMINESCENCE

摘要

In this paper we demonstrate a new approach for simulation of microdisc problem in spherical co-ordinates and application it to solution of the non-steady state electrochemiluminescence (ECL) problem at a microdisc electrode. This approach allows also to investigate the progressive shift from an almost planar disc electrode to an almost complete sphere electrode (2D) by simple adjustment of the geometry parameters in program. Obtained numerical results: currents and ECL intensity gives good comparable results with traditional approaches -simulating microdisc problem in cylindrical co-ordinates and 1D sphere problem.
