Direct action of electromagnetic fields on fluids. Final report. Report on phase 2
Fluids with imbedded charges or currents can interact with electric and magnetic fields. The aspect of magnetofluid dynamics has been explored with particular reference to its possible application in pumping fluids and in the measurement of fluid flow. A charge-injection/electric-field pump has the advantage that electric power is converted directly into fluid power, in a simple device, with no moving parts; the main disadvantage is that the technique is limited to very low pressures (10,000 Pascal, or less). The study of magnetic-fluid interactions led to the development of a device for flow measurement applicable to all fluids, whether insulating or conducting. It is based on the fact that a potential gradient is generated in a fluid that moves in a magnetic field. Such a magnetic transducer can be built very simply and inexpensively, using a permanent magnet as the source of the exciting field. The device covers a wide range of fluid velocities, and is independent of fluid properties and of flow regime.
