Flow regimes of two immiscible liquids are experimentally investigated in a rectangular
microchannel using a water–oil system. Oil-water viscosity ratios are varied from 0.2 to 75 …

Liquid–liquid dispersion by head-on impingement in a cross-slot microfluidic device to form
oil-in-water emulsion is experimentally investigated at broad range of flow rate conditions …

We report the results of a comparative study of microfluidic emulsification of liquids with
different viscosities. Depending on the properties of the fluids and their rates of flow …

The formation of droplets in an immiscible liquid in the presence of different surfactants was
studied experimentally using a flow-focusing microchannel. A low viscosity silicone oil (4.6 …

The formation of water-in-oil disperse flows is investigated in a microfluidic device. The
liquid–liquid flow mainly differs from these presented in the existing literature in its high …

Drop formation in a microfluidic flow-focusing device (cross-junction) was studied in
absence and presence of one of two ionic surfactants. Four different flow regimes …

The formation of an aqueous droplet in an organic continuous phase was studied
experimentally inside a flow-focusing microchannel (190 μm× 195 μm: depth× width) in the …

Although many aspects of microchannel emulsification have been covered in literature, one
major uncharted area is the effect of viscosity of both phases on droplet size in the stable …

Microfluidic flow-focusing systems are simple and cheap devices to produce monodisperse
emulsions. The objective of the study is to determine the flow conditions to create water-in …

A numerical research is conducted to investigate the triple emulsion droplet generation in a
three-dimensional axisymmetric flow-focusing device. The simulation predicts three flow …
