Experiments on Liquid-Vapour Phase Change between Plane Liquid Surfaces. Part 3: Results from a Closed Quartz Chamber

摘要

Results are presented of phase change experiments performed with mercury contained in a closed quartz chamber. The use of the special chamber permitted better control on contamination and also the possibility of running at higher temperatures. The present results emphatically confirm the large temperature jumps at the interfaces reported earlier in Part 2 of this study. Mild partially inverted and mild globally inverted temperature profiles were also observed. These mild inversions could possibly be due to non-uniform heating and cooling of the apparatus, three dimensional effects etc. For a conclusive confirmation of the existence of temperature inversion the problem of contamination of the liquid and vapor remains a major hurdle.
