Electrochemical digital simulation: incorporation of the Crank—Nicolson scheme and n-point boundary expression into the Rudolph algorithm

Abstract

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