A Practical Study of The Thermal Performance of a Vacuum Tube For Solar Collector Using a Double -Sided Electronic Curtain With Nano-Fluid

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