This SpringerBrief presents a recent advancement in modeling and measurement of the effect of
surface wettability on the defrost process. Carefully controlled laboratory measurements of the
defrosting of cooled surfaces are used to reveal the effect of surface wetting properties on
the extent and speed of frost removal by melting or slumping. The experiments are accompanied
by visualization of frost removal at several defrosting conditions. Analysis breaks the defrost
process into three stages according to the behavior of the meltwater. Surface wetting factors
are included and become significant when sufficient meltwater accumulates between the
saturated frost layer and the surface. The book is aimed at researchers practicing engineers
and graduate students.
