摘要
We study the capillary rise of wetting liquids in the corners of different geometries and show that the meniscus rises without limit following the universal law: h(t)/a approximate to (gamma t/eta a)(1/3), where gamma and eta stand for the surface tension and viscosity of the liquid while a = root gamma/rho g is the capillary length, based on the liquid density rho and gravity g. This law is universal in the sense that it does not depend on the geometry of the corner.
