Transient Analysis of Two-Phase Natural-Circulation Systems

A Review of two-phase flow dynamic instabilities in tube boiling systems

“…He found out that interconnecting the channels and increasing the relative size of the subcooled length had a stabilizing effect, while exit throttling had a destabilizing effect. Wallis and Heasley [43], Anderson et al [44] and Jain [45] studied the effect of inlet and exit restrictions. They found that an inlet restriction, which increased single-phase flow friction, had a stabilizing effect, while an exit restriction, which increased the two-phase friction, reduced the flow instability.…”
