The process of photo thermal evaporation in nano fluids finds promising applications in solar energetics, medicine and process technology. Previous studies report highly efficient production of solar steam in fluids with gold nano particles. In this article, we establish the process in nano fluids with less expensive carbon black (CB) and iron oxide (IO) nano particles (NP).
Screening the concentration of nano particles, we tailor the nano fluids to reach the efficiency maxima: 66% at 3% wt. (CBNP) and 75% at 10% wt (IONP); the steam was super heated up to 10 K (CBNP) and 16 K (IONP). It was also discovered that the IONPs-generated steam was contaminated with nano particles. In addition to experimental results, we have developed an empirical model of photo-thermal steam generation in nano fluids. The model agrees well with the experiments.
