Abstract
The experimental results on the action of a transverse magnetic field on the ejection process of an electrically conducting liquids are discussed in the article. The experiments have been carried out for two cases: keeping feeding power supplied to a pump constant for creating an ejecting flow, when the magnetic field changes, and keeping flowrate of an ejecting flow constant, too. It is shown that in the first case, in spite of increasing of the ejection coefficient with the magnetic field increasing, the integral flowrate in the ejector diminishes. In the second case the ejection coefficient and integral flowrate increase, but at the same time power supplied to an ejecting flow sufficiently increases. In the magnetic field a pattern of a flow changes greatly due to development of M-shapes. Figs 5, refs 1.
