“…It is important to design by figuring out what these errors are and what they mean for how well PTC works. Donga et al [5] studied the influence of receiver location on the optical and thermal performance of a PTC. The simulation was carried out by coupling MCRT heat flux distribution data with CFD.…”

The present work is aimed at geometrical optimization and optical analysis of a small-sized parabolic trough collector (PTC). Improving the performance of parabolic trough collectors can greatly justify the use of solar energy. An optimized curvature geometry, the location of the absorber tube, and the heat flux distribution along the circumference of the absorber tube are major features in the geometric optimization and optical modelling of parabolic trough collectors. Rim angle, aperture width, the diameter of the absorber tube, receiver position, and the optimum value of heat flux are the major parameters considered in this work for geometrical and optical analysis. The Monte Carlo ray tracing method has been adopted for analysis. The non-uniform heat flux distribution profile obtained from optical analysis of the proposed parabolic trough collector has been compared with the profile available in the literature, and good agreement has been obtained, which proves the feasibility and reliability of the model and method used for this study. An experimental new small-sized parabolic trough collector has been fabricated for the optimized rim angle of 90 deg after a successful laser light feasibility test. The effect of the absorber tube position along the optical axis on the heat flux profile was analysed and found to be substantial. Furthermore, the sensitivity analysis of the parabolic trough collector using the software applied has been discussed separately.

“…Donga et al investigated the impact of receiver position error on thermal and optical efficiency in PTC systems. Researchers found that the collector thermal efficiency drops by 14% for the position error of 1.63% from the focal point [12]. Afsharpanah et al numerically investigated the impact of using different types of twisted tapes in PTC systems for performance enhancement.…”

In this study, a novel non-tracking parabolic trough collector (PTC) is developed and experimentally investigated under North Cyprus climate conditions for residential water heating applications. Within the study, the impact of solar radiation (SR) and water volumetric flow rate (VFR) on the system performance is evaluated based on the testing results. Experiments were performed in the first and third weeks of April in Famagusta, in which SR is limited due to the rain and cloudy sky. The system is tested with water VFRs of 15 L/h and 20 L/h. During the tests, collector inlet/outlet temperatures also water tank, and ambient temperatures were measured. Furthermore, the solar intensity was also measured and recorded. Average SR on PTC surface, during the testing with 15 L/h and 20 L/h, was determined as 654.5 W and 723.3 W respectively. Study results showed that the useful heat gain from PTC was 285.2 W and 233.7 W, for the same order of VFRs. Moreover, the average thermal efficiency of the system was found as 44% and 33% for the VFRs of 15 L/h and 20 L/h respectively.

Summary This work presents an experimental evaluation of a new design of a parabolic trough solar collector (PTC). To maximize the energy yield, a solar tracking system is implemented. The thermal performance of the PTC at three outdoor test methods is evaluated. The new design essentially affects the balloon, the trunk, the insulation, the inner reflector, the glass, the upper plane reflector, and the cover. The system performance with bi‐axial orientation and an absorber with a glass‐covered envelope is compared with two other designs of mono‐ and bi‐axial orientation without a glass‐covered envelope. The tests of the PTC with an aperture area of 2.88 m2 were conducted in Tunisian weather conditions, and the results are compared with similar systems already published data in the literature. A dynamic simulation with TRNSYS software is developed to evaluate the system performance based on experimental results. An economic study to evaluate the system's feasibility is conducted. The results showed that the new design achieved a maximum temperature of 179°C in comparison to 134 and 120°C for the mono‐ and bi‐axial orientation without a glass‐covered envelope, respectively. Furthermore, in the new PTC design, the useful daily energy gain increased by 33% and 15%, and the system thermal efficiency increased by 8.9% and 5.8% in summer and winter, respectively, in comparison to the case of mono‐axial orientation without a glass envelope. Besides, the maximum useful energy gain and the instantaneous thermal efficiency in the new design were 22.6 MJ and 73.45%, respectively, in comparison to 17.93 MJ and 67.41% for the mono‐axial orientation without a glass‐covered envelope. The gross payback period of the system was found to be 3.3 years with an NPV of €5257 over the lifetime of the system.
