At 900 seconds, just before crystallization began, the maximum value of the film velocity was about 1.1 mm/min. The mathematical model of surface conden- sation and evaporation was useful in perform- ing transient simulations of film formation and removal. Several problems were considered to validate the model, and there was good agree- ment with the experimental data [1] .
