ELECTROCHEMICAL DIGITAL-SIMULATION - INCORPORATION OF THE CRANK-NICOLSON SCHEME AND N-POINT BOUNDARY EXPRESSION INTO THE RUDOLPH ALGORITHM

The Rudolph algorithm for solving coupled multispecies mechanisms was described with the Laasonen (backward-implicit) scheme and two-point b oundary expressions. This paper uses the Rudolph approach but with the more accurate Crank-Nicolson scheme and general n-point boundary expr essions. Example computations are reported for a simple catalytic mech anism (potential jump) and a more complex second-order catalytic mecha nism (LSV).
