Optical efficiency measurement of solar receiver tubes: A testbed and case studies

Case Studies in Thermal Engineering, 2018
Knowledge of the parabolic-trough collector (PTC) solar receiver performance is essential in solar thermal power plants using this type of collector technology because it is the component responsible for collecting the solar radiation and transferring it

Analytical Modeling of DSG in Parabolic Trough Solar Collectors [PDF]

Proceedings of the ISES Solar World Congress 2011, 2011
Direct steam generation (DSG) in the absorber pipes of parabolic trough solar collectors is a promising procedure since the thermal fluid is water instead of thermal oil, as conventional solar concentrating systems use. It enables higher cycle temperatures and efficiencies, reducing the cost of the system.

Digital Twin of a One‐Sun‐Driven Luminescent‐Concentrator‐Assisted Planar Solar‐Pumped Fiber Laser

Advanced Optical Materials, Volume 14, Issue 30, 14 August 2026.
An experimentally‐validated digital twin of a one‐sun solar‐pumped fiber laser enables a design exhibit 13‐times higher output power at 1064 nm to be achieved. Despite its simple appearance, the multitude of choices in the design parameters make finding this improved very tedious in the lab, thus the digital twin can save significant time and effort ...

Testing and Modeling of Direct Steam Generating Parabolic Trough Collectors [PDF]

Proceedings of EuroSun 2018, 2018
The present work is elaborated in the framework of the REELCOOP research project. A mini hybrid (solar/biomass) power plant was installed and is under testing at ENIT (Ecole Nationale d’Ingénieurs de Tunis), Tunisia. The power plant relies on Parabolic Trough Collectors (PTC) operating with Direct Steam Generation (DSG), an Organic Rankine Cycle (ORC ...

Synthesis of 4‐Hydroxyacetophenone‐Derived Bis‐Schiff Bases as Potent Cholinesterase Inhibitors: In Vitro Evaluation, Molecular Docking, DFT, and ADMET Analysis

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
A series of 4‐hydroxyacetophenone‐based bis‐Schiff bases were synthesized as dual cholinesterase inhibitors. Compound 2i showed the highest AChE and BuChE inhibition, supported by molecular docking, DFT, QTAIM, and ADMET studies. SAR analysis revealed the role of methoxy substitution in enhancing activity, highlighting 2i as a promising lead candidate ...

Experimental Thermal Performance Investigation of Nontracking Multiple Parabolic Trough Collector With a Single Absorber

Energy Science &Engineering, Volume 14, Issue 8, Page 3584-3607, August 2026.
With a mass flow rate of 0.3 kg/min, a direct solar radiation of 770.25 W/m2, and a global solar radiation of 915.25 W/m2, the maximum outlet water temperature was 63.3°C, the maximum instantaneous efficiency was 51.78%, and the average heat gain was found between 69.81 and 206.88 W, depending on mass flow rate and direct solar radiation.
