Abstract


Objectives: The objective of this paper is to review the heat transfer of Nano fluid in water as a base fluid in Flat-Plate Solar Collectors, and provide an optimal solution to improve the heat transfer. Methods/Statistical Analysis: This study used a sample of the heat exchanger consists of three small solar collectors which a copper tube passes from each of them, and there is a surface area the size of 1*0.15m2. The current cycle was analyzed using the amount of energy stored to transfer the heat. Findings: In constant Reynolds number, the convective heat transfer coefficient of Nano-fluids in the heat-absorbing pipes (with concentration 1000ppm) is slightly greater than that used the water as working fluid. Also in the concentration 10000ppm, this rate is doubled. Application: The findings concluded that the use of Nano-fluid in flatplate solar collector reduces the total heat loss coefficient of solar collector, and obtains the amount of more heat energy.
