Abstract

The rise of a large gas bubble or slug in a micro two-phase closed thermosyphon with a thin wire insert has been analyzed by the potential flow theory. The effect of the interfacial surface tension is explicitly accounted by application of the Kelvin-Laplace equation and solved for the bubble shape. The solution is expressed in terms of the Stokes stream function which consists of infinite series of Bessel functions.
The conditions of the bubble movement in a micro two-phase closed thermosyphon were theoretically ascertained.
