Three-phase contact expansion during the bubble adhesion on an inclined plane

Popis výsledku v původním jazyce

The bubble attachment onto a collecting surface is a common natural phenomenon and the bubble-particle interactions are used in numerous industrial applications. The adhesion process between a small single rising bubble and a stationary solid particle with hydrophobic surface in stagnant liquid is studied in this project. Experiments were performed using a freely rising bubble method. The influence of bubble size and type of bubble surface mobility was studied and described both experimentally and theoretically. Two mathematical models were used for theoretical description of the TPC expansion. According to our results, hydrodynamic model is not appropriate for the TPC line calculation. The molecular-kinetic model gives better results. Two adjustable parameters were calculated and their values correspond to the physical assumptions. It was found that the bubble size is the most important parameter influencing the TPC line expansion. The influence of bubble surface mobility is surprisin
