Synthetic jet actuator
Synthetic jet flow can be developed in a number of ways, such as with an electromagnetic driver (e.g. plasma actuator), a piezoelectric driver, or even a mechanical driver such as a piston. Each moves a membrane or diaphragm up and down hundreds of times per second, sucking the surrounding fluid into a chamber and then expelling it. Although the mechanism is fairly simple, extremely fast cycling requires high-level engineering to produce a device that will last in industri… WebTo optimize your artificial lift program you have to know what’s happening down hole.
