Abstract : The ion-drag effect in which like-charge ions generated by corona are forced through a dielec tric fluid by an electric field is investigated as a means of pressurizing fluids without the use of moving mechanical parts. A thrust bearing and a pump operating on this principle are studied both theoretically and experimentally. A mineral oil is used in the experiment as the working fluid. The effect is found to be quite small although flow rates greater than those obtained by previous investigators are observed. Experi ments verified the analytic results of the pump and thrust bearing study. Other currents than the like-charge ionic current were found present. Also, the pressure effect decreased with time when mineral oil was used as the pumping medium. (Author)
