Abstract
The paper demonstrates that more useful information can be extracted from the
boiling analysis by consistently incorporating gross turbulence characteristics
and appropriate local volume and time averaging.
Keywords: heat transfer, nucleate boiling, flow boiling.
1 Introduction
Common practice in thermal engineering today is to use empirical correlations
for heat transfer. Advances in the knowledge like turbulence modeling in two
phase flow, tracing the history of origination of bubbles, droplets etc., dynamic
two-phase flow pattern recognition etc., require more information from the heat
transfer models like haw to consider the deviation from the developed
turbulence, haw to provide internal characteristics of boiling like bubble
departure diameters and frequencies and others. This paper demonstrates that
more information can be exhausted from the analysis by consistently
incorporating even of gross turbulence characteristics in the analysis and
appropriate local volume and time averaging.
Keywords
heat transfer, nucleate boiling, flow boiling.
