Linear capillary breakup of a liquid jet in the uniform droplet singlet oxygen generator

In the study of the uniform droplet singlet oxygen generator,the breakup of a round jet into the droplet stream is a vital technology.The disturbance applied threw by the piezoelectric transducer to the stream grow on the surface of the stream.The growth of the disturbance continues exponentially until a fluid parcel,is pinched off of the capillary.Analysis shows that several parameters affect the growth rate of the disturbance.The increase in the surface tension of the stream fluid and the decrease in the orifice diameter enhance the growth rate of the disturbance.The other parameters have less effect on the growth rate of the disturbance.The relatively broad bandwidth of the curve in the paper reveals that there are many potential growth rates on the surface that can theoretically determine the breakup of the jet into droplets.Hence,it will be the combination of rate and initial disturbance amplitude which pinches off the fluid into the desired droplets that we strive to control.
