Enhancing evaporation rates are of great practical interest in many technological applications such as water desalination or drying in industry. Since the conventional methods of increasing evaporation viz. increasing temperature, surface area etc. may not be always practically feasible or economical, novel methods of evaporation enhancement are necessary. The current study explores the possibility of evaporation enhancement by introducing a Tetrafluoroethane gas ambient under different conditions of heating and circulation. Depending upon the temperature and circulation conditions, as enhancement of 58 to 375% in evaporation rate has been measured and physical explanations into the underlying mechanism have been suggested.

Enhancing evaporation rates are of great practical interest in many technological applications, such as water desalination or drying in industry. Evaporation mass flux is a function of ambient temperature, relative humidity, and velocity of the air passing over it. Since the conventional methods of increasing evaporation, namely increasing temperature, surface
