Résumé

The two-dimensional characteristics of the boiling two-phase flow of liquid helium in a duct are numerically investigated to realize the further development and high performance of new cryogenic engineering applications. First, the governing equations are presented and several flow characteristics are numerically calculated, taking into account superfluidity. Then, the two-dimensional structure of the boiling two-phase flow of liquid helium is shown in detail. Next, it is clarified that the distributions of the void fraction, the velocity field and the instantaneous streamline of two-phase superfluid helium flow show a tendency different from those of normal fluid helium. According to these theoretical results, the fundamental characteristics of the cryogenic boiling two-phase flow are predicted.
