Control of Jets by Very Small Signals

It is very important that a very small signal can control flow fields for selection of various control methods. Author developed a method to control the jets by very small signal in process of investigating flow fields of turbulent opposed jets. That is to say, a very thin cylinder in the jet center can control an impact position and also turbulence in the jet center play an important role. Many methods are acceptable to produce the turbulence in the jet center. And we can select various physical phenomena for input to control the jet flow fields. Here I propose a method using an arc discharge to control the axisymmetric jets.
