Résumé
The main aim of these studies is to examine the process of rupture of water bridge between two glass spheres during its convective evaporation or mechanical extension. Evolution of bridge profile was recorded with use of high-speed camera, with frame rate up to 54000 frames per second, and subsequently digitalized. Digital image processing allows to determine several geometrical parameters: curvature of the surface of the water body (gorge radius, external shape radius), water wire dimensions, satellite drop radius. Basing on these parameters time evolution of following parameters was calculated: capillary force (gorge method) and suction and surface tension force components, frequency of oscillation of satellite droplet and remaining water caps, capillary force jump.
