Pump effect of an electrical vortex flow in a corrugated pipe

The main result of this experimental and theoretical investigation was the discovery of a pump effect of the electrical vortex flow in a channel with insulated asymmetrically corrugated walls. It was established that the pressure of the liquid is created in the direction established above: sudden expansion-gradual contraction of the channel. The pressure, with a high degree of accuracy, linearly increases along the channel length, which indicates the smallness of end and other secondary effects. The dependence of the average pressure gradient on the square of the current has a linear character
