Modelling and analysis of the effect of different parameters on a parabolic-trough concentrating solar system

Concentrating solar power technologies are potential energy-harvesting systems. This paper simulates and analyzes the design of a parabolic-trough concentrating solar system. Optimum measurements are sought for the receiver, and collector performance is investigated using three heat transfer fluids, namely, ammonia, nitrogen, and carbon dioxide. Receiver parameters are optimized to achieve the maximum thermal efficiency of the collector. The concentration ratio, collector aperture area, and mass flow rate of the fluids significantly influenced the collector's efficiency and the heat removal factor.
