Query: Computational Fluid Dynamics Study of Taylor Flow in
  Microreactors:Investigating the Effect of Surface Tension and Contact Angle
  on the Heatand Mass Transfer   Microfluidics technology offers high efficiency of heat and mass transfer and
low safety hazards compared to conventional multiphase processes. The
multiphase flow in the microchannels is usually characterized as Taylor flow
that includes elongated microbubbles , separated by liquid slugs. In the
current study, we employ OpenFOAM CFD package to investigate the effect of the
surface tension and the contact angle on the interfacial surface area and
transport yield in microscale systems. The results show that contact angle can
significantly affect the surface area and the bubble size while the surface
tension does not change these parameters in the system. Moreover, in lower
contact angle, the flow may turn into bubbly flow, affecting $K_L$, mass
transfer coefficient in the liquid phase. Findings of the current study can
improve the mass transfer coefficient in microreactors while avoiding thermal
runaways, hot spots and other safety issues of conventional reactors.
