Abstract
A synthetic jet actuator includes a housing, a first chamber formed in the housing and filled with a gas, a second chamber formed in the housing to connect to the first chamber and filled with a liquid, an orifice formed to penetrate the housing and which connects the first chamber to the outside, and a heater which generates a bubble by heating the liquid filling the second chamber. As the bubble is generated and terminated inside the liquid in the second chamber by the heater, a volume of the first chamber is periodically changed so that a jet is generated at an outlet of the orifice.
Claims13
A synthetic jet actuator comprising:
- a housing;
- a first chamber formed in the housing and filled with a gas;
- a second chamber formed in the housing to connect to the first chamber and filled with a liquid;
- an orifice formed to penetrate the housing and which connects the first chamber to the outside;
- and
- a heater which generates a bubble by heating the liquid filling the second chamber,
- wherein, as the bubble is generated and terminated inside the liquid in the second chamber by the heater, a volume of the first chamber is periodically changed so that a jet is generated at an outlet of the orifice.
A synthetic jet actuator array comprising a plurality of synthetic jet actuators, wherein each of the synthetic jet actuators includes:
- a housing;
- a first chamber formed in the housing and filled with a gas;
- a second chamber formed in the housing to connect to the first chamber and filled with a liquid;
- an orifice formed to penetrate the housing and which connects the first chamber to the outside;
- and
- a heater which generates a bubble by heating the liquid filling the second chamber.
