Work published in a number of papers and resulting from a research
programme is briefly reviewed. The publications cover three aspects
of heat transfer in two-phase liquid–vapour systems:
(1) heat transfer to boiling liquids on a solid surface
with some process induced convection (pool
(2) heat transfer to boiling liquids in vertical tubes
in which convection plays a significant part and
is due to the process induced natural circulation
(3) the effect of physical properties, particularly of binary
mixtures, on heat transfer in boiling.
The work in the area of pool boiling and in the area of physical
properties of binary mixtures was undertaken as an auxiliary programme
to provide information and data for a rational approach to the more
complex and industrially important problem of heat transfer in natural
circulation reboilers. All the published papers in the area of research
defined here are quoted in full.
Also briefly presented is the work—as yet unpublished—in which
the correlation of flow boiling heat transfer data already published is
revised. The revision was necessary in view of the experimental
evidence that gravitational forces influencing hydrodynamic flow patterns
were not adequately taken into account in the previous correlations.
