The capillary number is the ratio of viscous force to the capillary force, while Weber number is the ratio of the inertial force to the capillary force.
is the creator of a new method of liquid vaporization -- the Capillary Force Vaporizer (CFV).
The innovative technology utilizes the capillary force vaporizer, which is about the size of an aspirin tablet and made of ceramic discs.
Gyrolab systems use precise, automated control of centrifugal and capillary forces to steer liquid flow through nanoliter-scale microfluidic structures contained within Gyrolab CDs, automating the assay workflow.
It will be based on integrating thermoresponsive polymers on top of strongly adsorbing solids, where the temperature gradient generated by asymmetric irradiation will cause imbalanced capillary forces leading to drop motion.
These microscopic cavities induce capillary forces that keep sanitizers outside the concave areas.
The tensile stress, which is normally attributed to capillary forces due to water menisci, either plateaus or decreases over time due to water evaporation or polymer relaxation.
However, capillary forces alone can induce liquid flow (albeit very low), and this can be an attractive alternative to the complexity of active actuation.
