Abstract

The phase change rate and related physical constants of superheated water at the liquid surface can be determined by the mechanism of hydrogen bonding and by the Maxwell‐Boltzmann principle. In this paper, we introduce a physical constant and attempted to demonstrate the existence and the value of this physical constant. First, we measured temperature fluctuations under the bubbles in a pool of boiling water. Second, a sample analytical model was introduced, to determine the value of the physical constant. Comparisons were made between the experimental data and those of the calculations. Β© 2002 Wiley Periodicals, Inc.

## Abstract Experiments on pool boiling of water were performed under decompression. Temperature fluctuation was measured with three thermocouples which were equipped on the copper block surface by plating. Rapid temperature drops in this fluctuation arise at the same times. This shows the existenc
