Abstract
In the present atricle the experimental data on the work of an ejector, in which ejecting Q1 and ejected flow Q2 of a conducting liquid are separated by a nonconducting wall have been discussed. Transfer of hydraulic energy from the first flow to the second one in such an ejector is performed by electrodynamic interaction. The goal of the experiment was to determine the value of secondary flow rate Q2 or ejector coefficient n = Q2/Q1 depending on flow rate Q1 and external magnetic field B. The experiments were carried out both at constant ejecting pump power and constant flow rate Q1 for different magnetic fields. Basing on the experimental data a comparison of efficiency for a hydrodynamic and an electrodynamic ejector was made. It has been shown that an electrodynamic ejector is more effective.
