Engineering Physics Annotation << Back THE FORMATION OF NANOBUBBLE ON WATER-ROUGH SURFACE BOUNDARY S.I. KOSHORIDZE Thermodynamic analysis of the formation of equilibrium nanobubble on the water- rough hydrophobic interface is carried out with taking into account Kelvin capillarity formula and charge of bubble. The roughness is taken into account by means of a conical fossa on the surface. It is shown that at certain values of the radius of the bubbles, the Gibbs energy passes through the minimum, that corresponds to equilibrium nanobubble. Key words: surface nanobubble, capillary pressure, Kelvin formula, Gibbs energy. DOI: 10.25791/infizik.11.2019.1010 Contacts: - Pp. 25-29.
