Abstract This paper investigates the impact of Marangoni phenomena for low concentrations of 2-propanol/water and methanol/water mixtures. In real
systems the addition of small levels of surface-active contaminants can affect the surface tension of the liquid-vapor interface and thermodynamic
conditions in this region. Analysis was performed for three widely accepted binary mixture correlations to predict heat flux and superheat values for
subatmospheric experimental data using bulk fluid and film thermodynamic properties. Due to the non-ideal nature of these alcohol/water mixtures,
this study also employs an average pseudo single-component (PSC) coefficient in place of an ideal heat transfer coefficient (HTC) to improve… More >
