摘要

SIAM 应用数学杂志》第 84 卷第 3 期第 1039-1059 页，2024 年 6 月。摘要考虑由均质材料制成的两个等半径平行实心圆柱体组成的系统。我们研究了两个实心圆柱之间圆柱形液桥的稳定性。研究证明，如果圆柱形液体是凹形的，那么它是稳定的。如果圆柱形液体是凸的，我们建立了圆柱形液体半径和接触角的条件，确保长凸圆柱形不稳定。给出了这些凸圆柱的长度估计值。

Stability of a Capillary Circular Cylinder between Two Parallel Cylinders

SIAM Journal on Applied Mathematics, Volume 84, Issue 3, Page 1039-1059, June 2024.
Abstract. Consider a system of two parallel solid cylinders of equal radius made of a homogeneous material. We study the stability of a liquid bridge of circular cylinder shape between both solid cylinders. It is proved that if the circular cylinder liquid is concave, then it is stable. If the circular cylinder liquid is convex, we establish conditions on the radius of the cylinder liquid and the contact angle that ensure that long convex circular cylinders are not stable. Estimates for the length of these convex cylinders are given.
