Mechanistic models for pool nucleate boiling heat transfer: input and validation
Correlations for nucleate boiling heat transfer should be improved, or
in the long term possibly be replaced, by the development of mechanistic
simulations that include the non-uniform spacing and variable
characteristics of the nucleation sites and non-linear interactions
between the sites. This paper discusses the interactions that should be
included in simulations and some lessons from a first attempt to
validate a particular simulation against experimental spatio-temporal
data for wall temperature. Input data for nucleation site positions and
characteristics are a particular problem and the prospects for obtaining
this data from measurements that are independent of boiling are
discussed
