Abstract

We present experimental results and theoretical considerations on the boiling mechanisms in a closed two-phase thermosyphon in order to define the frontiers between the main boiling regimes and the heat transfer characteristics.
We first review the boiling regimes, the causes of the unsteady operations and the correlations describing the frontiers between the main regimes. Then we review the correlations to estimate the heat transfer coefficients at the evaporator and the condenser. Experimental data are in good agreement with the proposed correlations.
