Abstract:
A comprehensive review of the findings that punctuated
ten years of research on dropwise evaporative cooling is
presented. The first studies consider a single droplet
evaporating on a high thermal conductivity solid
surface. The solid-liquid coupling is addressed when
considering the case of a low thermal conductivity
solid. A powerful, non-intrusive, infrared
thermographic technique is instrumental in describing
the thermal behavior of the solid surface. The
applications relevant to fire suppression suggest the
input of radiant heat from above the surface instead of
heat conducted through the solid. Once the single
droplet behavior is fully documented experimentally and
accurately modelled, the study of sparse water sprays is
undertaken. A superposition model is formulated which
well represents the experimental data.
