Mathematical modeling of capillary flow of viscous fluid

[摘要] We consider flow of viscous fluid in the capillaries under assumption that the contact angle of the curve varies over the length of the capillary. For the two laws of change we obtain estimates of the distance of meniscus from its initial position and reduction of its movement speed. It was found that the results of the evaluations are consistent with the existing physical concepts.
