Microchannels with curved geometries have been employed for many applications in
microfluidic devices in the past decades. The Dean vortices generated in such geometries …

A double T-type microchannel consisting of two T-junctions is used as the base unit of tree-
like microchannels. Studying the breakup process and behavior of bubbles in T-type …

Porous media have been widely used for liquid-gas separation, benefiting from the strong
capillary force generated from the micro/nanoscale pores. Understanding the flow …

Large sections of gas accumulation easily form in continuously undulating liquid pipelines to
impede the commissioning process affecting the safe operation of the pipeline. To solve the …

We numerically study the dynamics of buoyancy-driven bubbles in a constricted vertical
capillary in which a throat with an arc shape is present. To investigate at what conditions and …

Understanding of mass transfer in gas-liquid slug flow is imperative to design and optimize
micro-reactors. There exist extensive studies on symmetric bubbles by the phase volume …

In view of the practical importance of gas–liquid two-phase flow in many applications, such
as chemical engineering, petroleum engineering, nuclear engineering, etc., a reliable model …

The passage of a bubble and the required energy for its motion through a confining pore can
potentially be affected by the surface roughness and geometry of the pore. The motion of an …

Two-phase gas–liquid stratified flow is characterized by a structure in which the gas and
liquid phases are separated from each other by a continuous interface. Adequately …

The change in the internal pressure of an isolated dispersed phase passing through a
confined geometry can be determined by tracking its deformation. While some research has …
