https://www.iiste.org/Journals/index.php/APTA/article/view/62130
<p>Solar energy is widely regarded as a very promising alternative energy source due to its potential to satisfy a substantial portion of global energy demand. The efficacy of a solar concentrator is contingent upon operational and weather factors. This paper presents an experimental evaluation of the effect of tilt angle and mass flow rate on the effectiveness of a parabolic trough solar concentrator</p> <p>The parabolic trough solar collector was subjected to experimental testing in LAUTECH's Ogbomoso engineering facility. It has a collector length of 2.1m, an aperture width of 1.2m, an adjustable rim angle of 75<sup>o</sup>, 90<sup>o,</sup> and 105<sup>o</sup>, a focal length of 30 cm, a 10-liter storage reservoir with varying flow rates of 0.0004 m<sup>3</sup>/s, 0.0008m<sup>3</sup>/s, and 0.0012m<sup>3</sup>/s. The temperatures were measured with a 12-channel temperature recorder (SD data logger), while the solar radiation was measured with a solar meter and water was used as a working fluid. Thermal performance analysis was conducted to ascertain the impact of tilt angle, mass flow rate, and weather conditions on the solar concentrator's effectiveness.</p> <p>The results indicate that the system has a greater thermal efficacy with weather elements such as solar intensity and ambient temperature at higher mass flow rates and a 90<sup>o</sup> tilt angle. This concentrator aids the energy industry by decreasing reliance on electricity and pollution from fossil fuels, thereby minimizing environmental and health issues.</p> <p><strong>Keywords</strong>: Alternative Energy, Concentrator, Effectiveness, Environment, Tilt Angle,</p> <p>DOI: 10.7176/APTA/88-01</p> <p>Publication date: February 28th 2024</p>Itabiyi O.
