Abstract
A longitudinal stretching based wave pumping system and corresponding methods. A stretchable tube is configured to hold a fluid. An actuator is coupled to the tube. The actuator is configured to longitudinally stretch and release the stretchable tube to create waves on the stretchable tube and within the fluid that propagate and reflect at one or more reflection sites along the stretchable tube to create wave pumping, which drives the fluid and generates net flow in a flow direction.
Claims20
A pumping system, comprising:
- a stretchable tube, the stretchable tube configured to hold a fluid;
- and
- an actuator coupled to the tube, the actuator configured to longitudinally stretch and release the stretchable tube to create waves on the stretchable tube and within the fluid that propagate and reflect at one or more reflection sites along the stretchable tube to create wave pumping, which drives the fluid and generates net flow in a flow direction.
