Study of three-phase contact line expansion during the adhesion of bubble on solid surface
Original language description
This work is part of project, which deals with mutual interactions of bubbles and particles. Interactions can be described by three steps - collision (approach of bubble and particle to the contact distance and their subsequent collision), attachment (adhesion of bubble on particle surface) and stability of bubble-particle agregate (or deattachment). Adhesion (which is studied) of bubble involves the thinning and rupture of wetting thin film and the expansion and relaxation of three phase contact line (TPC, gas-liquid-solid). TPC expansion can be characterized using attachment time which includes sliding time and time of TPC expansion and the lenght of TPC line. Experiments are carried out by scanning (high-speed kamera) bubble adhering on a solid surface. Using the image analysis are evaluated contact times and length of TPC line.
