Shape of liquid meniscus
Webb5 juli 2024 · The meniscus shape under different heating power is displayed. The effects of key parameters such as the vapor space thickness, wick thickness, and the supporting columns arrangement on the heat transfer performance of the UTVC are analyzed. WebbThe upper surface of a liquid in a tube is called the meniscus, and the shape of the meniscus depends on the relative strengths of the cohesive and adhesive forces. In …

WebbT 1= Force due to surface tension at the liquid-solid interface. T 2= Force due to surface tension at the air-solid interface. T 3= Force due to surface tension at the air-liquid interface. For the equilibrium of the drop, T 2=T 1+T 3cosθ. cosθ= T 3T 2−T 1.
WebbIf the surface has about the same affinity for the liquid as the liquid does for itself, then the liquid will form a hemispherical shape on it. If the surface has less affinity for the liquid … WebbMeniscus shape. (A) The calculated shape of the meniscus along the white line in Figure 4. Radial distances and surface elevations are calculated from the apex of the meniscus. Negative...
Webb1 aug. 2007 · It is a general assumption that the meniscus is of nearly spherical shape in a cylindrical capillary tube (Rand, 1978). The true shape of meniscus is still unknown as interface image near...

The centre of coordinates is … population based study とはWebb24 feb. 2024 · For an obtuse angle of contact, which is greater than 90 degrees, the liquid meniscus will have a concave shape. This is because the adhesive forces between the liquid molecules and the solid surface are stronger than the cohesive forces between the liquid molecules. population-based studiesWebbThe model developed can be used for accurate prediction of three-dimensional meniscus shape on structured surfaces with micro/nano-scale features, which is necessary for … population-based studyWebbΔ P h = ρ g h. whereas the capillary pressure is. Δ P c = 2 γ R = 2 γ cos θ r. So balancing these we get our 'famous' equation: h = 2 γ cos θ ρ g r. Now we have a situation in which the height of our tube above the liquid, h m a x is smaller than h.
