Analytical Study on the Behavior of the Bubble in the Micro Two-Phase Closed Thermosyphon

초소형 밀폐형 이상 써모싸이폰 기포의 거동에 관한 해석적인 연구

The rise of a large gas bubble or slug in a Micro Two-Phase Closed Thermosyphon with a thin wire insert has been analiged 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 an infinite series of Bessel functions. The conditions of the bubble movement in a Micro Two-Phase Closed Thermosyphon were theoretically ascertained.
