THIN LIQUID FILM EVAPORATION IN A VERTICAL CHANNEL. INFLUENCES OF EVLET LIQUID TEMPERATURE AND IMPOSED WALL HEAT FLUX
ABSTRAKT
This study concerns the evaporation of a finite liquid film flowing on one of the walls of a vertical canal, 2m high. The canal consists of two parallel plates separated by the distance e. The wall on which the liquid flows is submitted to a constant heat flux, the other wall is thermally isolated (an adiabatic wall). To the forced convection due to the flow of air which enters the canal at uniform speed, is added the force of natural convection by the flow of heat imposed on the heated wall. The influences of inlet liquid temperature and imposed wall heat flux on the liquid Nusselt number at the liquid-wall interface are examined in detail.
