“…Zhang et al [12,13] studied the steam carrying effect in static flash of both pure water and aqueous NaCl solution. Muthunayagam et al [14] developed a vapor diffusion model to estimate the variations of droplet temperature and diameter during evaporation process of a saline water droplet at low temperatures and reduced pressures. Liu et al [15] constructed a mathematical model to simulate the evaporation process of a saline droplet during depressurization.…”

This paper reports an experimental and numerical study of evaporation process of a two-volatile bicomponent (ethanol/water and acetic acid/water) droplet during depressurization. The environmental pressure, the ambient temperature, and the droplet temperature are investigated during the experiments. A mathematic model is then constructed to simulate the droplet evaporation process. The model solves one-dimensional heat conduction equation and species diffusion equation to acquire the temperature distribution and the concentration distribution inside the droplet. The activity coefficient is introduced to imitate the vapor partial pressure at the droplet surface. By numerical calculations, the variations of temperature distribution and concentration distribution within the ethanol/water droplet and the acetic acid/water droplet are discussed. The effects of composition, final ambient pressure and initial droplet diameter on droplet evaporation are also analyzed in the current study. Results show that the model predictions agree well with the measured temperature data, demonstrating the soundness of the present model and providing insight into the complex heat and mass transfer during the evaporation process of a bicomponent droplet under depressurization.

“…The LPV could be a promising technique for this aim. Muthunayagam et al (2005) have used the low-pressure-vaporization of saline water for the production of fresh water, and they achieved a yield between 3% and 4%.…”

“…Several researchers developed mathematical models and conducted numerical studies to simulate the phenomena of the LPV (Dostal, 2002;Jin and Xu, 2006b;Aoki, 2000;Muthunayagam et al, 2005). Jin and Xu (2006a) and Aoki (2000) developed detailed and complete mathematical models to simulate the LPV of water.…”

“…Another approach to obtain passively created vacuum conditions for solar flash desalination is investigated with both experimental and simulation studies by Abutayeh et al [10]. Muthanayagam et al [11] describe another experimental approach for seawater desalination via flash evaporation. They suggest using seawater from different depths and thus different temperatures for feed and cooling water, respectively.…”
