POOL BOILING ON THIN HEATERS: THE ROLE OF THERMAL INTERACTION AMONG VAPOR STEMS
Résumé
We examine the issue of thermal interactions within
a heater as a possible explanation for conflicting critical
heat flux data on thin heaters, as reported by various
investigators. While heater thermal properties have been
considered in previous studies, the focus of this study is
the interaction between the thermal transport process
within the heater and the distribution of nucleation sites
on the heater surface. It is shown that the spatial
distribution of stems on the heater surface, as well as the
size distribution of these stems, can affect the average
surface temperatures. Such interactions are greater as the
heater thickness decreases.
