Abstract

The stability of axisymmetric, long liquid bridges held captive between two coaxial, circular solid disks kept at different temperatures is considered. Because of the temperature difference between the supporting disks, a thermally-induced surface tension gradient and its associated flow (Marangoni convection) appear in the liquid column, modifying (decreasing) the capillary stability of the bridge. The influence on the stability limits of long, axisymmetric liquid bridges of the combined effect of gravity acceleration and thermally induced surface tension gradients was experimentally analyzed by using very small size liquid bridges (between disks 1 mm in diameter). Experimental results are compared with available analytical results.
