Simulation of experiments to measure surface tension by the shape of a drop surface at the existance of irregularity in its hanger or bearing

South Ural State University

Abstract: We suggest a technique to determine surface shape for a drop suspended to a hanger of an arbitrary form and orientation in space. This technique allows researchers to obtain geometrical characteristics (such as volume, surface area, cross-sectional areas) of the drop suspended to a flawed hanger, and to find experimental errors in determining surface tension that are associated with using such hanger. Our numerical experiments show that the main source of error in determining surface tension is braking of circular symmetry of the hanger.

Keywords: surface tension measurements, the shape of a drop, numerical methods.
