The influence of particles on jet breakoff
Summary
Particles in a vibrated nozzle affect liquid jet breakup length. Phase determines if particle disturbances shorten or lengthen the jet, impacting cell sorting applications.
Area of Science:
- Fluid dynamics
- Biophysics
Background:
- Liquid jet breakup is crucial in various applications.
- Nozzle vibration influences jet stability and droplet formation.
Purpose of the Study:
- To investigate the effect of particles on vibrated liquid jet breakup.
- To understand how particle-induced disturbances interact with nozzle vibration.
Main Methods:
- Experimental observation of liquid jets issuing from a vibrated nozzle.
- Analysis of particle-induced surface disturbances and their phase relationship with nozzle vibration.
Main Results:
- Particles passing through the nozzle orifice create surface disturbances.
- These disturbances can either augment or counteract nozzle vibration effects.
- Jet breakoff length is modulated (shortened or lengthened) based on phase.
Conclusions:
- Particle-nozzle vibration phase is critical for controlling jet breakup.
- Findings have implications for optimizing cell sorting in fluorescence-activated cell sorters.
