Three-phase contact expansion during the bubble adhesion on an inlcined plane
Original language description
The aim of this project is to describe the three-phase contact (TPC) line expansion. The influence of bubble size and type of surface bubble mobility are studied. Experiments were performed using a freely rising bubble method; bubbles with diameter up to1 mm were generated and the prism with an inclined plane with hydrophobic surface was used as a solid particle. The whole process was recorded using high-speed digital camera and images were evaluated using the image analysis software. Two mathematicalmodels were used for theoretical description. According to our results, the hydrodynamic model is not appropriate for the TPC line diameter calculation. The molecular-kinetic model gives better results and values of two adjustable parameters correspond to the physical assumptions. It was found out that the bubble size is the most important parameter influencing the TPC expansion whereas the influence of bubble surface mobility is surprisingly low.
