In the theory of inkjet technology

First, the theory of aerodynamic interference, CASTLEMAN first proposed the theory of aerodynamic interference. He believes that due to the aerodynamic interference effects between the jet and the surrounding gas, the volatility of the instability is produced on the surface of the jet. With the growth in length, the surface wave is affected by the increasingly unstable shorter, until microns and then spread over the fog jet. Second, the theory of pressure fluctuations, this theoretical system that provides fluid pressure fluctuations affect the atomization process. Thus, under popular pressure variations in the injection system can often ensure that it plays a significant role in the injection spray nozzle.Third, chaos theory, this theory consider the spraying process jets happening inside the nozzle, and chaotic fluid can play an important role. Someone also found that the radial component of the velocity of the fluid from the turbulent jet flow at the nozzle exit pipe, in the mist. Wednesday, air turbulence theory, attitude contrary to the theory of chaotic disturbance, he believes that the large amplitude pressure disturbances in the fuel injection system caused by spraying. Thursday, boundary conditions mutation theory, the boundary conditions of the mutant believe that mutations occur at the nozzle exit and the boundary conditions of the fluid (internal pressure).

Completion of nozzle theory

There are shortcomings in the mechanism nozzles opportunities and even contradictory. Most scholars, as Bracco FV intervention support of aerodynamic theory. Hypotheses to explain fully biodegradable low-speed jet stream and high-speed and can be used as fog causes. Now the fuel injection nozzle was investigated in two ways in and out of the water: first, by using digital to create a series of research hypotheses model number model, moreover, use advanced technology to capture the photovoltaic check the details of the injection process to provide support for this hypothesis.
