Surface tension measurement: attempt to combine pendant drop and deformed drop retraction methods
Original language description
The deformed drop retraction method of boundary tension measurement is based on evaluation of ellipsoid droplet relaxation published by Luciani and Utracki. The pendant drop method is based on evaluation of equilibrium drop shape. When it is applied to viscous liquids, drop shape equilibrates during a certain time similarly as for ellipsoid droplets. This text presents an attempt to apply deformed drop retraction procedure to pendant drop in order to obtain alternative boundary tension estimate. However, the results for testing sample strongly differ from correct surface tensions. The usage of formula for ellipsoid relaxation is a weak point of the estimate presented. The challenge remaining for the future is to describe the relaxation of pendant drop.
