3. Modeling hot air or electric anti-icing
Evaporation is the most important part of modeling dry (total evaporation) or wet (partial evaporation) anti-icing systems. Various models are presented. Two physical models exist:
a model based on the gross difference in mass concentration (in fact all models except Spalding), coupled with the Colburn-Chilton analogy for the transfer coefficient. Various simplifying assumptions are made to arrive at a final formulation, but the basic physics remains the same;
a model based on a diffusion law, integrated on a plane Couette flow (Spalding model).
The main models used are described below.

Vaporization is generated by the...
