abstract = {The fundamental equations of Dirac{\textquoteright}s new classical electrodynamics cannot be solved with the conventional perturbation method because there is no possibility of setting the coupling constant e equal to zero to start with. A perturbation method is worked out under the assumption that the charge is small, which means that the field created by the charge is neglected in the zero-order approximation. A general solution for the case of irrotational flow and another one for small vorticity are given. The equations derived are not easily soluble for large vorticity.},
