Dewetting behaviour of liquid bridges stretched by an accelerated plate
Liquid bridge stretching is of interest for a wide field of industrial applications like printing and coating, but also for the functioning of aircraft engines because of its importance in the process of ice crystal icing. In the present experimental study, the focus lies on describing the geometry of the liquid bridge during the stretching process with respect to midpoint diameter, contact line diameter and contact angle for constant accelerations from 10 m/s2 up to 180 m/s2. The observed evolution of the dynamic contact angle is described as a function of the capillary number. For the early phase of the stretching process relations for the curvature and midpoint diameter are proposed.
