Název v původním jazyce

Description of the bubble shape on a planar solid surface with variable inclination angle

Popis výsledku v původním jazyce

Three-phase contact line expansion can be theoretically described using two models - hydrodynamic and molecular-kinetic. Both of these models were originally developed for the interaction of the bubble and the horizontal plane in pure water. It was proved experimentally that the molecular-kinetic model is suitable also for conditions of an inclined plane. But in this case the adhering bubble is not symmetric (as in the case of a horizontal plane) and contact angles on the right and left side of the bubble are different. The knowledge of contact angles is very important for using the model, for the calculation is necessary to know, how the contact angle (left and right) changes during the adhesion. The aim of this project is to figure out methodology for calculations of contact angles on the left and right side of the bubble separately using modificated ADSA (axisymmetric drop shape analysis) method.
