要約

Using the holographic interferometry and the high speed cinematography heat transfer at the phase interface of vapour bubbles condensing in subcooled liquid of the same substance was measured with ethanol, propanol, refrigerant R 113 and water. The holographic interferometry gave also information on the boundary layer conditions at the liquid side, representing the main heat transfer barrier. The measurements were performed in the range 2<Pr<15 and l<Ja<120. Measured data could be well correlated as functions of Prandtl- and Reynolds-number for heat transfer and of Archimedes-, Prandtl-and Jacob-number for bubble collapse time.
