It is found that even splitting of the droplet flow is accompanied by blocking splitting, whereas uneven splitting is accompanied by non-blocking splitting or non-splitting.
The wettability features of the T-junction have significant effects on the droplet splitting modes. The droplet sizes are subjected to image analysis to study the polydispersity of the mother and daughter droplets at the inlet and two arms of the T-junctions. How the wall wettability affects the phase-splitting features of the mini-T-junction is studied carefully. Water and silicone oil are selected as the working fluids. This paper reports an experimental study of the steady-state and statistical phase-splitting features of droplet/slug flow split in a mini-T-junction with a hydraulic diameter of ∼ 1 mm.
