    摘要: A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. The control flow is introduced through multiple control flow ports surrounding the primary nozzle and adjacent to the Coanda surface. By selectively opening and closing different control flow ports the motion and profile of the jet can be controlled.

    摘要: Disclosed are embodiments of apparatus for sorting particles in a fluid stream by size. In one embodiment of an apparatus for sorting such particles, a housing is provided, which defines a channel for a fluid stream containing particles. A suction channel is also provided, which terminates at a suction port. The suction port is positioned adjacent to the fluid stream. The suction channel may be configured to create a low pressure region and thereby redirect particles in the first fluid stream such that they may be sorted by size.

    摘要: In a first preferred embodiment for an improved synthetic jet actuator, the orifice shape is altered by either a flap or adjusting the housing walls. If the flap is deployed outward from the wall just above the orifice of a synthetic jet actuator, the synthetic jet flow will be vectored upward, toward the flap. Similarly, if the upper wall forming the orifice is moved outward from the jet chamber interior with respect to an opposing wall forming the orifice, the flow will also vector upward. In the second preferred embodiment of an improved synthetic jet actuator, an opening in addition to the orifice, may be formed in one or more walls of the housing. A louver is aligned with the opening in the housing and permits fluid flow in only one direction, either into the chamber or out of the chamber. When the louver permits fluid flow into the chamber, the jet actuator can operate at high speeds since fluid can enter the chamber through a greater surface area. Another preferred embodiment for an improved synthetic jet actuator comprises two concentric tubular sections normal to an outside surface of a solid body). In operation, the innermost section is connected to a vacuum device and constantly pulls fluid down its length from the ambient fluid above the outer surface. Meanwhile, the outer section ejects fluid into the ambient environment by pulses. Such an operation will cause a synthetic fluid jet to form above the constant suction synthetic jet actuator.

In one illustrative embodiment of an apparatus for separating such particles, a housing is provided, which defines a channel for a fluid stream containing particles. A suction channel is provided, which terminates at a suction port. The suction port is positioned adjacent to the fluid stream. A blowing channel terminating at a blowing port is also provided. The blowing port is positioned adjacent to the suction port such that the suction port is positioned in between the fluid stream and the blowing port. The blowing port and the suction port are configured to create a low pressure region and thereby redirect the first fluid stream towards the low pressure region.

    摘要: A thermoacoustic cooling system for cooling an object such as a microelectronic chip. Heat produced by the object is transferred to a thermoacoustic engine. The thermoacoustic engine may include a resonator defining a chamber. A stack may be positioned in the chamber with one side of the stack adjacent to the heat source, and the opposite side of the stack adjacent to air in the chamber having a relatively cooler temperature. One or more orifices may be formed in the resonator such that the acoustic power generated by the thermoacoustic engine creates a synthetic jet to circulate air and move the air away from the object being cooled. Thus, the heat produced by the object is used to power the thermoacoustic engine to thereby remove heat from the object. The thermoacoustic engine may use no moving parts and may require no external power source other than the object being cooled.

    摘要: A device is disclosed that uses a flow-control methodology to control sprays at very high precision and frequency. The device is based on an enhanced Coanda effect. The control flow is selectively applied to the region in which we desire the jet to vector and control the profile (width) of the jet. In one embodiment, the control flow is applied at the desired circumferential location by the action of a rotting disk with a flow passage of a size that spreads the jet the desired amount. The size of this flow passage may be controlled by using two overlapping disks with large holes in each. By rotating one disk relative to the other, the size of the resultant passage can be modified.
