Foam formation
WebFoam is a collection of small bubbles of air that accumulate on or near the surface of the fluid. In severe cases, the foam can leak out of the machine through breathers, sight glasses and dipsticks. Foam is an efficient thermal insulator, so the temperature of the oil can become difficult to control. Webis based on foam film behaviour and the techniques for controlling the foam liquid content, developed by the authors. A major contribution represents the independent consideration of formation and stability of foam films in theoretical and experimental aspects. No monograph published so far reveals these topics in the mentioned manner.
