Study of the three-phase contact expansion during the bubble adhesion on a hydrophobic solid surface
Original language description
This contribution deals with bubble adhesion on particle surface which consists of three steps - the liquid film thinning, the film rupture and expansion of the three phase contact (TPC). Three-phase contact line expansion can be described using molecular-kinetic model. This model is based on the theoretical description of the bubble contact angle on the three-phase interface. These contact angles change dramatically from 180o to equilibium (Young) contact angle close to 90o. Modificated ADSA method isused for the contact angle calculation. Our experiments deal mainly with the interaction of the bubble with the inclined plane in the solution of surface active agents. The aim of the project is to describe the process of the TPC expansion during the adhesion of the bubble with the diameter up to 1 mm. The process of the adhesion was recorded using high-speed digital camera and images were evaluated using the image analysis software NIS-Elements. Calculations were performed using the Mat
