Profile of capillary bridges between two vertically stacked cylindrical fibers under gravitational effect

摘要: Abstract Although profiles of axisymmetric capillary bridges between two cylindrical fibers have been extensively studied, little research has reported on under external forces such as the gravitational force. This is because add significant complications to Laplace–Young equation, making it difficult predict drop based analytical approaches. In this paper, simulations vertically stacked with effect taken into consideration are studied. The asymmetrical structure that hard approaches was studied via a numerical approach Surface Evolver (SE). axial and circumferential spreading liquids identical in presence effects predicted determine when or can be neglected. liquid volume, equilibrium contact angle, distance fiber radii. simulation results were verified by comparing them experimental measurements. Based SE simulations, curves representing along obtained. scaled difference upper lower fibers.
