Abstract:
A micromachined synthetic jet apparatus placed in an environment having an ambient fluid, comprising:(a) a substrate material defining a cavity having a volume of the ambient fluid and one orifice on a face of said substrate for allowing fluid communication between said cavity and the environment; and (b) a volume changing means for changing a volume within said cavity so that when said cavity volume is increased, a portion of the ambient fluid is drawn into said cavity, and when said cavity volume is decreased a portion of the ambient fluid is emitted from said orifice and forms a series of fluid vortices projected in the environment out from the orifice, wherein said vortices entrain a portion of the ambient fluid thereby generating a synthetic jet stream.
