Dynamic Behavior of a Meniscus Subjected to a Transient Acceleration Field.

Abstract

The dynamic response of an unheated meniscus within a capillary tube subjected to single and multiple cycle transient acceleration induced forces was studied experimentally and analytically. A capillary tube was partially filled with either water or ethyl alcohol and mounted on a centrifuge for visual observation of the dynamic response of the meniscus subject to an acceleration transient. A one-dimensional mathematical model was formulated to predict the dynamic response of the meniscus and compared with experimental results. For the case in which the meniscus was heated, thermocapillary stresses in the near contact line region were accounted for in the model by a change in contact angle.
