Parabolic Trough Solar Collector

To a closed type parabolic trough solar collector, thermal performance was analyzed, a mathematical model was set up, and test-bed of collector to heat efficiency test was built. According to the experiment test data, the accuracy of the thermal mathematics model was validated. The results show that the model simulation accuracy is so higher that the model is reasonable and available.

Practical Investigation

This paper describes an experimental model for estimating parabolic trough solar collector performance, as the Arduino micro-controller technology was applied to improve the optical and thermal efficiency of the system. The receiving tubes of different internal diameters (2mm, 6mm) were implemented to evaluate system performance. The practical investigation of the solar concentrator was conducted to generate steam at moderate temperatures, as the experiments were executed in Baghdad with geographical coordinates (33° 18' N, 44° 21' E) during specific days. The results showed the effectiveness of small diameters, as the significant enhancement of thermal performance was at a flow rate of 8 L/h and receiver tube diameters of 2 mm, as the improvement was 30% compared to 6 mm tubes.
