✦ Synopsis
Critical heat flux in a two-phase thermosyphon is usually dealt with in one of two different ways: one uses the maximum falling liquid rate obtained from the envelope method, the other uses the instability. We first clarify the difference between the maximum and the instability criteria. The CHF in the thermosyphon is shown to be well predicted by the maximum liquid rate obtained using the maximum criterion and this prediction is better than that using the instability criterion. This comparison implies that CHF phenomenon in a thermosyphon is caused by the falling liquid reaching a maximum value rather than by instability of the falling liquid on the interface.
