Abstract
We investigate the two-component Nernst–Planck–Debye system by a numerical study of self-similar solutions using the Runge–Kutta method of order four and comparing the results obtained with the solutions of a one-component system. Properties of the solutions indicated by numerical simulations are proved and an existence result is established based on comparison arguments for singular ordinary differential equations.
