Synchronization and control of capillary flows in rectangular microchannel with spacers [PDF]
Biomicrofluidics, 2020 Liquid control in microchannels is quite important in microfluidic devices used in, for example, lab-on-a-chip and point-of-care applications. Capillary microfluidics, being self-powered, is especially advantageous for use in passive devices, and has ...

Patterning Lines by Capillary Flows
Nano Letters, 2006 We report that capillary flows in an evaporating thin film create line patterns, with widths ranging from a few micrometers to less than 100 nm. Deliberate patterning of such lines requires contact-line pinning and the presence of foaming surfactants ...

Some generic capillary-driven flows
International Journal of Multiphase Flow, 2006 This paper deals with numerical simulations of some capillary-driven flows. The focus is on the wetting phenomenon in sintering-like flows and in the imbibition of liquids into a porous medium.

A kinetic model for capillary flows in MEMS
AIP Conference Proceedings, 2012 A kinetic model for the study of capillary flows in micromechanical devices has been presented. The model is based on the Enskog-Vlasov kinetic equation and provides a reasonable description of two-phase flows and of fluid-surface interaction.

Wetting considerations in capillary rise and imbibition in closed square tubes and open rectangular cross-section channels [PDF]
, 2013 The spontaneous capillary-driven filling of microchannels is important for a wide range of applications. These channels are often rectangular in cross-section, can be closed or open, and horizontal or vertically orientated.

A suitable parametrization to simulate slug flows with the Volume-Of-Fluid method [PDF]
, 2012 Diffuse–interface methods, such as the Volume-Of-Fluid method, are often used to simulate complex multiphase flows even if they require significant computation time.

Microsecond relaxation processes in shear and extensional flows of weakly elastic polymer solutions
, 2012 In this paper, we introduce an experimental protocol to reliably determine extensional relaxation times from capillary thinning experiments of weakly elastic dilute polymer solutions. Relaxation times for polystyrene in diethyl phthalate solutions as low

NEWTONIAN FLOW IN CONVERGING-DIVERGING CAPILLARIES [PDF]
International Journal of Modeling, Simulation, and Scientific Computing, 2013 The one-dimensional Navier–Stokes equations are used to derive analytical expressions for the relation between pressure and volumetric flow rate in capillaries of five different converging-diverging axisymmetric geometries for Newtonian fluids. The results are compared to previously derived expressions for the same geometries using the lubrication ...

Journal of the Society of Materials Science, Japan, 1967 Blood flowing in capillary cannot be treated as a homogeneous fluid, since the diameter of capillary is of the same dimension as that of red cells. The hematocrit is about 45%. Therefore, when blood flows in capillary, the width of the“compartment”between the two adjacent red cells will be nearly equal to the thickness of the red cell.

Flow and clogging of capillary droplets
Soft MatterWe present the deformable particle model that recapitulates capillary droplet structure and dynamics during flows through constrictions. We then show that large droplet deformability causes slow flows and promotes droplet clogging in obstacle arrays.
