Abstract
An arrangement for influencing a liquid flow includes a first section selectively configurable to provide a vortex generator surface, the vortex generator surface comprising a series of laterally aligned projections, to induce vortices in the liquid flow.
Claims9
An arrangement for influencing a liquid flow, the arrangement comprising:
- a first section selectively configurable to provide a vortex generator surface at a leading edge of the first section, the vortex generator surface comprising a series of laterally aligned projections, to induce vortices in the liquid flow;
- a second section downstream of the vortex generator surface and the first section;
- and
- an actuator assembly comprising at least one actuator for extending the vortex generator surface between an extended position away from the second section and a retracted position back toward the second section;
- wherein, in the extended position, the vortex generator surface increases a vorticity magnitude of the liquid flow, and, in the retracted position, the vortex generator surface decreases the vorticity magnitude of the liquid flow.
A method of influencing a liquid flow in an arrangement comprising a first section selectively configurable to provide a vortex generator surface comprising a series of laterally aligned projections at a leading edge of the first section, a second section downstream of the vortex generator surface and the first section, and an actuator assembly comprising at least one actuator for extending the vortex generator surface between an extended position away from the second section and a retracted position back toward the second section, the method comprising:
- configuring the first section to provide the vortex generator surface to induce vortices in the liquid flow,
- wherein, in the extended position, the vortex generator surface increases a vorticity magnitude of the liquid flow, and, in the retracted position, the vortex generator surface decreases the vorticity magnitude of the liquid flow.
