| Since the solar energy is from the most well-known and important sources of clean energies, the solutions to absorb solar energy play significant role in the effectiveness of thermal collector system. The present study aims to investigate the experimental analysis of solar volume collector’s performance for usage in domestic solar water heater and using graphene oxide nanoplatelets nanofluid based deionized water. The weight percentage of graphene oxide/deionized water has been chosen with the percentages of 0.005, 0.015 and 0.045, respectively. The used collector has been tested according to the standard of EN 12975-2 in different temperatures of inlet fluid and in flow rates of 0.0075, 0.015 and 0.225 kg/s. The results of this experiment determine that with the increase of nanofluid’s weight percentage, the collector efficiency is increased and collector efficiency in its highest level in the flow rate of 0.015kg/s and in the weight percentages of 0.005, 0.015 and 0.045 are 63.28, 72.59 and 75.07 respectively, which this amount for the base fluid is 58/25. | ||
