Abstract

This research aims to investigate the performance of solar water collector by varying: mass flow rate, inclination angle, total solar radiation, pipe size, and number of glass covers. The test rig was established to collect the data for the whole months of September and October and use it as a focal point for analysis of the solar water heating system's performance. The dynamic behavior was simulated and optimized with MATLAB software for the practical data to investigate the performance of the flat plate solar collector. The novelty in this study is the first time the authors use the whole practical data instead of average data to approximate the theoretical dynamic investigation of the flat plate solar collector. The achievements are as follows: the collector'sefficiency was increased from 62.17% to 71.26% when the collector pipe spacing was reduced from 186 mm to 86 mm; the increase in efficiency was approximately 2% as the collector pipeline diameter increased from 1 mm to 50 mm; the optimum efficiency was achieved with triple glazing and was about 0.83%; the mass flow rate increases from 1 to 5 liters per minute, so it improves the efficiency of the system from 64% to 83%. Moreover, the best tilt angle for the flat plate solar collector was 30°. Also, the heat loss coefficient was raised by around 50% when wind speed was increased from 1 m/s to 5 m/s. Thus, the use of dynamic investigation with actual data will assist the researchers in improving the performance of the solar water flat plate collector.
