要約

This paper shows how subcooling influences even fully developed boiling heat transfer. This influence is audibly accompanied by a change of sound emission. Experimental results with water as test fluid reveal that the heat transfer coefficient in first approximation does not only depend on the heat flux and the reduced pressure but also on the Jakob number. The latter dependency is not uniformly directed - it reverses while subcooling is increased. Beyond a critical value, different boiling modes may substitute or supply each other in a spatio-temporal alternation on the heating surface. Consequently, boiling curves with contradicting behavior appear. A calculation method based on a simplified model is proposed and compared with experimental results.
