Экспериментальное Исследование Подъема Уровня Жидкости В Плоском Капилляре, Образуемом Эластичными Периодически Растягиваемыми Стенками

Abstract

A water rise in a plane capillary with elastic periodically stretched walls is experimentally demonstrated. Dependence of the water meniscus rise height on the value of time-periodic elastic extension of capillary walls was measured. A deviation of the measured dependence from the linear dependence was recorded. The latter one could be realized in the mode of an ideal pinning of a meniscus edge.
