Аннотация

Heat transfer across falling film along a heated wall was studied both experimentally and analytically.
Experiment in which water film falls along a heated vertical wall with counter-current vapor updraft was conducted at elevated pressure in order to match the ECCS injection condition in BWR LOCA.
Analytical treatment was made by taking into consideration the turbulent structure of the falling film. Special consideration was made to the shear stresses acting on the film surface. Comparison with the experimental data proved the validity of the present analysis.
