...Pushpendra Singh; M. K. Gaur; G. N. Tiwari; Anil Kumar Thermal model is developed to predict the outlet water temperature with respect to time for water-in-tube type evacuated solar collector connected in series. Developed mathematical expression is validated for the single collector and two...

... term use. In this work a new multistage evacuated solar desalination system was proposed and designed. The objective of this work is to increase the productivity and improve the low efficiency of the traditional solar desalination systems. The new system works by virtue of the higher evaporation rate...
