ABSTRACT:
A method for controlling fluid flow. A fluid (560) can be communicated to a first fluid flow port (105) disposed adjacent to a first surface (196) of a rotatable disk (115) of a homopolar motor. The fluid can flow through at least one orifice (130) in the rotatable disk to a second fluid flow port (110). The rotation of the disk can be selectively controlled to vary a fluid flow rate. Further, the disk can be rotated to align a selected one of the orifices with at least one of the first and second fluid flow ports. In another arrangement, the shape of the orifice can have a radial width that increases in a circumferential direction.
