Heat transfer characteristics of a two-phase, air-water direct contact evaporator

The purpose of the research was to carry out an experimental and theoretical investigation of the heat transfer on a direct contact column for desalination purposes. The effect of air and water mass flow rates and air inlet temperature on the temperature distribution and moisture content of the air outlet stream was measured. The experimental heat transfer coefficient was estimated and, in order to simulate the experimental results, a comparison with available correlations was performed
