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. |
