    摘要： A magnetohydrodynamic (MHD) micropump and microsensor which utilizes micromachining to integrate the electrodes with microchannels and includes a magnet for producing magnetic fields perpendicular to both the electrical current direction and the fluid flow direction. The magnet can also be micromachined and integrated with the micropump using existing technology. The MHD micropump, for example, can generate continuous, reversible flow, with readily controllable flow rates. The flow can be reversed by either reversing the electrical current flow or reversing the magnetic field. By mismatching the electrodes, a swirling vortex flow can be generated for potential mixing applications. No moving parts are necessary and the dead volume is minimal. The micropumps can be placed at any position in a fluidic circuit and a combination of micropumps can generate fluidic plugs and valves.

    摘要： An MHD apparatus includes a solenoid coil that is symmetrically positioned about a central axis aperture. Upon energization, the coil produces an intense magnetic field along the central axis and within the aperture. A first cylinder having a first diameter is positioned in the aperture and a second cylinder which exhibits a second diameter that is less than the first diameter is positioned within the first cylinder. A helical web insulator is positioned between the first cylinder and the second cylinder and provides a helical fluid flow channel between first and second ends of the cylinders. A DC power supply is connected between the first and second cylinders, which produces a current flow that interacts with the magnetic field to exert an MHD propulsive force on seawater within the fluid flow channel. In this mode of operation, the apparatus pumps the saltwater or provides a thrust. When a flow of a conductive fluid is introduced through the helical channel, it enables an electric potential between the first cylinder and the second cylinder in the presence of the axial magnetic field. In this mode of operation, the apparatus delivers an output current when connected to a load. The MHD apparatus thus exhibits a relatively long path wherein the seawater interacts with both the radial electric field and the axial magnetic field.

    摘要： A thrust generator including a superconducting solenoid magnet 1, a thrust duct 2 and a power supply device 3. The spiral portion of the thrust duct 2 is inserted in the hollow interior of the superconducting solenoid magnet 1. Anode 8 and cathode 9 are fixed at both inner walls of the thrust duct 2. Electric power is supplied to an electromagnetic fluid 10 in the duct 2 to produce a magnetic field and a Lorentz's force f. The electromagnetic fluid 10 flows into the thrust duct 2 through an opening 6a at the inlet end portion 6 where it is urged continuously by the Lorentz's force F and jetted outside from an opening 7a at the outlet end portion 7. The reaction of the jet force becomes a thrust. A Lorentz's force f, generated by the superconducting solenoid magnet 1 and by the current J flowing through each current feed element, rotates and drives the thrust duct 2.

    摘要： A method and an apparatus for propelling water vehicles in surrounding water are disclosed. The water has carriers of electrical charge. For propelling the water vehicle, the latter is provided with an elongate pipe being immersed in the water for allowing the water to flow therethrough along a longitudinal axis thereof. An electric field (E) is generated within the pipe with electric field lines extending radially with respect to the longitudinal axis. Further, a magnetic field is also generated within the pipe, the magnetic field having field lines extending circumferentially about the longitudinal axis. Thereby, a force (F) is exerted upon the charge carriers by simultaneous action of the electric field (E) and the magnetic field (B) on the charge carriers. The force (F) is directed parallel to the longitudinal axis to thereby propel the water vehicle.
