Capillary phenomena. XII. Properties of fluid bridges between solids in a gravitational field

摘要: Capillary phenomena associated with fluid bridges between the ends of two vertically positioned cylindrical rods a common axis have been elucidated by using methods used previously for pendent and sessile drops, emergent captive bubbles, holms. Meridian curves which on rotation give found meeting boundary conditions at solid edges. Bridge volumes Vα as function bridge height Z⦵ obtained equal reduced radius, R = 0.5, 1, 2, 5; closed loops possible equilibrium configurations whose stability has also examined. Stability partly depends method manipulation system. Equilibrium paths variation height, i.e., rod separation, constant volume, volume chosen separation distance. The applied force upper (taken thin disk) pressure difference across interface evaluated these systems. cover range where instability is not expected contact angles θ 0° sides rods.
