Abstract
A generalization of the Thomson model to include field-enhanced dissoc iation in the bulk (the Onsager effect) and unipolar charge injection, without recombination between electrolytic and injected ions, is form ulated for nonpolar dielectric liquids. In the case of an autonomous i njection of charge, approximate analytical solutions are given for the dissociation and the injection current densities. A comparison with t he 'exact' numerical solution is done to determine the regions of vali dity of the approximate solutions. The general case of field-enhanced dissociation and nonautonomous injection also is investigated numerica lly.
