Intensification of the liquid film evaporation in a vertical channel

The experimentation consists in determining the flux of evaporation of the falling liquid film in natural and forced convection. The exploration of the thermal field (in the film and in the gas phase) allows us to give a description of evaporation in the channel. The results obtained are exploited to study the influence of the operating parameters such as the heat flux density on the temperature of liquid film and the evaporated flux for the two modes.
