Physical causes of water flow separation from the walls in a tray with a superhydrophobic coating (EN) / Физические причины отрыва потока воды от стенок в лотке с супергидрофобным покрытием (RU)

V. K. Verkholomov

Abstract: It is shown for the first time that when a liquid (water) slides along a hydrophobic surface, a turbulent boundary layer does not appear on it. For the first time, the physical reason for the lack of influence of liquid sliding on the reduction of the friction resistance of a textured hydrophobic coating under a turbulent flow regime has been established.

On heat of wetting (EN) / О теплоте смачивания (RU)

V. K. Verkholomov

Abstract: As a result of the analysis, it is shown that when a drop spreads in the solid/liquid/vapor system, the same horizontal and vertical adhesion forces simultaneously act on the side of the solid surface particles. The heat of wetting is equivalent to the work of vertical adhesion forces.

Flow separation at the water slide in an open tray with a superhydrophobic coating (EN) / Отрыв потока от стенок при скольжении воды в открытом лотке с супергидрофобным покрытием (RU)

V. K. Verkholomov

Abstract: The absence of scale factor influence on water sliding in an open tray with a superhydrophobic coating was experimentally established. In this case, the flow of water occurs with the separation of the flow from the side walls.
