Abstract

In this research, a practical study and appraisal of the thermal performance for the solar collector with vacuum tube has conducted Two types of nanomaterials (aluminum and aluminum oxide) have added to distilled water with nanoparticles diameters of 30 nm and 50 nm respectively. The nanomaterials were used in three several concentrations and three several flow rates which used as a working fluid in evacuated tube solar collector (ETSC) in order to increase the efficiency and beneficial thermal gain. An electronic double-sided reflective and absorbent electronic curtain were added to enhance the performance and control the temperature of the nanoscale. A clear improvement in efficiency was observed when using the reflective curtain that helped to speed up the Nano fluid heating and controlling the required temperature.

Highlights

  • Improving the performance of the evacuated tube solar collector by using the double- sided reflective electronic curtain.                                                                                        
  • Improving the thermal properties of the evacuated tube solar collector by using two types of nanomaterials, aluminum and aluminum.                                                                                   
  • The small size of the nanoparticles played an important role in improving the heat transfer.                                    
  • Increasing the rates of improving efficiency and useful heat gain by using the reflective electronic curtain.
