A mathematical model for two-dimensional calculation of 
the temperature and density of the steam in a steam-air mixture which 
rises between two water films flowing down adiabatic shields has been 
proposed. The parameters of the films have been calculated in a one-dimensional 
approximation. The results of calculating the parameters of air according 
to the one-dimensional and two-dimensional models of the processes 
of heat and mass transfer have been compared. The range of applicability 
of the former to a film-type heat and mass exchanger has been determined.
