Mathematical Simulation of Operating Modes of Absorption Water- Ammonia Refrigeration Unit Rectifier in the Systems for Producing Water from Atmospheric Air Using Solar Energy

The mathematical model of film flow modes with an upward flow of a steam mixture with a highly efficient heat removal in the forced convection mode has been developed. The parameters of the liquid film flow and the vapor flow (velocity and Reynolds number) were estimated for typical values of rectifier tubes diameters in 20, 32 and 40 mm. It was shown that the mode of film flow is laminar; of the steam flow – developed turbulent, and the thickness of the film is practically unchanged for the rectifier tubes dimensions under consideration.
