Abstract
A closed wall having an electrically conductive inner surface forming an electrode. A body is mounted within the wall cooperating with the wall to an orbital path for the flow of fluid, and a second conductive electrode passes through the center of the body. A flux field is induced parallel to the axis of the wall. An inlet and outlet are provided at opposite ends of the helical body for circulation of electrically conductive fluid, through the path perpendicular to the flux field.
Claims20
Magnetohydrodynamic apparatus comprising a container having a tubular conductive wall functioning as a first electrode, fluid port means spaced at the ends of said container for the ingress and egress of an electrically conductive fluid to and from said container, at least one divider disposed insulatingly from said wall in said container separating said container into at least two axially spaced compartments, a conductive rod forming a second electrode disposed insulatingly through said at least one divider along the center of said container, each of said compartments defining in cooperation with said wall and said rod an orbital pathway for the flow of said electrically conductive fluid, means for transferring fluid from one orbital pathway to the next adjacent orbital pathway, means for inducing a magnetic field across said orbitally moving fluid with a direction parallel to the axis of said container, and conductor means attached to each of said electrodes for the transfer of an electric current, to or from said device, produced by the interaction of said fluid and magnetic field.
Magnetohydrodynamic apparatus comprising a container having a tubular conductive wall functioning as a first electrode, a conductor rod disposed in said container and extending along a longitudinal axis functioning as a second electrode, fluid port means spaced at the ends of said container for the ingress and egress of an electrically conductive fluid to and from said container, at least two dividers disposed in said container about said second electrode separating said container into a plurality of axially spaced compartments allowing fluid to be held on the surface of said dividers, each of said dividers having a barrier disposed radially between the conductor rod and the wall to prevent the flow of fluid on the surface from being completely circular, and means located adjacent one side of said barrier for permitting flow of fluid from one divider to another, said at least two dividers being rotatively offset one from the other so that the fluid flowing from each divider passes onto the same relative side of the barriers and exits to the next divider from the opposite side of the barriers, thereby defining in cooperation with said wall an orbital pathway for the flow of said electrically conductive fluid, means for inducing a magnetic field crossing said orbital path with a direction parallel to the axis of said container, and conductor means attached to each of said electrodes for the transfer of an electric current, to or from said device, produced by the interaction of said fluid and magnetic field.
