In science:

Another important set of experimental observations was performed with fluids of different viscosities and equilibrium contact angles θe in a capillary tube: it was found that instability occurred if C a/θ3 e exceeds a critical value, strongly pointing to a hydrodynamic mechanism for the instability.

Either fibers with the according core- and buffer sizes need to be obtained, or fibers can be inserted into precision glass capillary tubes with close tolerance on the inner diameters to match the outer diameters of the fibers, or into a precision aperture plate.
Prototype development of the Integral-Field unit for VIRUS
The outer circles denote the capillary tubes used to set up the matrix with 340 µm pitch. Right: Possible layout of 143 IFUs (filled squares) for a full VIRUS. The fill factor is 1/9.

Capillary tube - (1), isolation gap - (2), (3)- molten location of wire.
Development of High Granulated Straw Chambers of Large Sizes
The information from the middle segment is read out over the contact wire going through the spacer supporting the capillary tube and the hole in the straw wall. To compare the signals going through the straw wall and its end plugs, the right anode segment is equipped with two readout outputs 3 and 4.
Development of High Granulated Straw Chambers of Large Sizes
When assembling the segmented anodes some capillary tubes are combined with the specialized polycarbonate spacers, forming "assembly units" (Fig.3), without preventing the passage of the gas mixture along the straw.

As a result we let the tubes in our network model behave as if they were hourglass shaped with respect to the capillary pressure.
A Numerical Study of Capillary and Viscous Drainage in Porous Media
Thus, the capillary pressure of a meniscus starts at zero when the meniscus enters the tube and increases towards a maximum value at the middle of the tube where the tube is most narrow, before the capillary pressure decreases to zero again when the meniscus leave the tube.

In the network model we treat the tubes as if they were hourglass shaped with respect to the capillary pressure.

Therefore, we let the capillary pressure depend on where the meniscus is situated in the tube.
A Numerical Study of Capillary and Viscous Drainage in Porous Media
Practically, the wetting angle of a meniscus and thereby its capillary pressure may generally be different depending on whether the meniscus retires from or invades the tube.
A Numerical Study of Capillary and Viscous Drainage in Porous Media
The capillary pressure pc,ij is the sum of the capillary pressures of each menisci [given by Eq. (2)] that are present inside the tube. A tube partially filled with both liquids is allowed to contain at maximum two menisci.
