Beschreibung
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.
Presents a new look at the defrost process wherein surface wettability is explicitly included in the mathematical analysis Advances the modeling paradigm beyond strictly diffusion-controlled prior models Adds new data to the field from experiments on carefully prepared surface with quantified properties Corroborates the major findings of the analysis through visualization of melting
