Abstract

In this work we investigate the effect of relative humidity and ambient temperature on the self-generated hydrothermal waves at the liquid-vapor interface of evaporating ethanol drops by means of infrared thermography and CCD camera. Absorption and/or condensation of water vapor onto the drop was found to have a strong impact on the thermal patterns retrieved at the drop interface. Furthermore, we make use of gas chromatography to quantify for the first time water absorbed and/or condensed onto the drop. To conclude, we highlight the importance to account for the heat of water absorption/condensation in order to characterize the complete heat and mass transfer problem during organic solvent drop evaporation.
