Flow focusing microencapsulation
WebJun 15, 2009 · Six flow modes are distinguished in the flow-focusing experiments of a liquid jet forced by a high-speed air stream. The domains of the modes are identified on the parameter space of the liquid flow rate Q l and the gas pressure drop Δ p g.The disturbance wavelength λ and breakup length L of the jet are also measured. A theoretical model … WebNov 1, 2024 · In flow-focusing, the dispersed phase flows through a nozzle until it joins the continuous phase. The shear stress is produced by a focus unit that abruptly narrows fluids' passage [34]. Flow-focusing geometry is more complex than a cross-flow one but remains popular since its leads to a better monodispersity with a higher production frequency ...
