Heat Transfer in Two-Phase Flow of Mixtures of Air and Water (2nd Report)

Abstract

In this report, following the previous report, the authors have experimentally investigated the heat transfer for the parallel upward flow of the mixtures of air and water in a vertical pipe. The results may be summarized as follows : (1) The coefficients of heat transfer by Verschoor and Stermerding are comparatively suitable for those obtained from this experiments. (2) The effects of dryness fraction upon the coefficient of the heat transfer have been made clear. (3) The empirical formula of heat transfer are shown and the applicable ranges are also discribed.
