External Meniscus on a Ribbon-Like Fiber

Аннотация

We consider the problem of configuration of the external meniscus formed by the capillary rise of a liquid during immersion of a ribbon-like fiber into the liquid. In the case when the fiber thickness is small, a new analytical solution of the problem is constructed using the asymptotic approach. In this solution, at the sharp edges of the fiber, the liquid level has a jump for all values of the contact angle different from π/2.
