The classical Nukiyama-Tanasawa equation commonly used for predicting the Sauter mean diameter of droplets (and in turn, collection efficiency) in venturi scrubbers, which has surface tension as a critical parameter, is only approximately applicable to water and water-alcohol mixtures and not to ...
Surface tension holds water droplets together and would make them spherical in the absence of other forces such as gravity, because a sphere has the smallest surface to volume ratio. Many animals take advantage of surface tension on ponds. Common insects called water striders, or pond skaters, ...

It was determined that the wettability of the nozzle inner wall and the surface tension of the ink are vital factors controlling the print quality and speed. Increasing the contact angle of the nozzle inner delays the droplet breakup time and reduces the droplet velocity. In contrast, higher ...
The smoothed particle hydrodynamics(SPH) method is a Lagrangian particle method with great potential for multi-phase flow simulations.Surface tension forces play important roles in many systems in both natural and artificial environments.This paper uses a continuum surface force(CSF) model and an inter...

Given the surface tension of water is γ = 72 mN/m, and the diameter of droplets is 3 mm, the estimated force that caused the difference in contact angles was around 0.03 mN. While the force needed to deflect droplets was estimated to be approximately 0.08 mN, this magnitude of ...
The critical surface tension is a measure of solid surface tension and is evaluated by the relationship between the measured contact angle of droplets and the surface tensions of liquids on a target solid surface [34, 35]. Concretely speaking, if the value of cosθ is plotted versus the ...
In the present invention, various sizes of non-wetting droplets are inserted into microtube devices of various shapes having therein a gas or wetting fluid which causes the droplets to movement in response to fluid pressure. The droplets may translate within a void of the microtube device which ...
