Abstract
A synthetic jet comprises structure (comprising at least one piezoelectric member) for defining a fluid chamber; a nozzle configured to provide fluid communication between the fluid chamber and external to the fluid chamber; and, a drive source connected to apply an electrical signal to the piezoelectric member in a manner whereby activation of the piezoelectric member causes zero net flux of fluid with respect to the fluid chamber.
Claims19
A synthetic jet comprising:
- means for defining a fluid chamber, the means for defining the fluid chamber comprising at least one piezoelectric member;
- a nozzle configured to provide fluid communication between the fluid chamber and external to the fluid chamber;
- a drive source connected to apply an electrical signal to the piezoelectric member in a manner whereby activation of the piezoelectric member causes zero net flux of fluid with respect to the fluid chamber.
A synthetic jet assembly comprising:
- a housing configured to define a fluid chamber;
- a displaceable diaphragm situated in the housing;
- the housing having a port defined therein for permitting ingress and egress of fluid to the fluid chamber;
- a conduit connected to the port;
- a drive source connected to apply an electrical signal to the diaphragm member in a manner whereby activation of the diaphragm facilitates creation of a standing pressure wave in the conduit;
- plural nozzles or orifices formed in the conduit, the plural nozzles or orifices being spaced apart at positions corresponding to pressure anti-nodes of the standing pressure wave.
