Investigation of heat exchange during sea water boiling in a horizontal thin film desalination plant

This paper describes the characteristic features of heat exchange during sea water boiling in a thin film on the heated surface of tubes with outer diameters of 16, 24, 32 mm over a wide range of heat fluxes, film loadings, pressures and initial sea water concentrations.On the basis of experimental data, we found two areas of flashing whose transient value is defined by q'. We obtained the equations for minimum and maximum film loadings and correlated the variables for heat transfer coefficient calculation.
