Abstract Parabolic trough solar collector systems are the most advanced concentrating power technology for large-scale generation purposes. The current work reviews various selective coating materials and their characteristics different designs in power. Solar absorbing coatings collect radiation convert it to heat. To promote higher efficiency lower energy costs at temperatures requires, this ...

Intensive energy penalty caused by CO2 separation process is a critical obstacle for retrofitting power plant with carbon capture technology. Therefore, the concept of utilizing solar to assist solvent regeneration post-combustion proposed recently as promising pathway compensate efficiency reduction derived from process. However, feasibility solar-assisted technologies largely depends on types...

The present study reports a novel concept of a direct solar thermal collector that harnesses the localized surface plasmon of metallic nanoparticles suspended in water. At the plasmon resonance frequency, the absorption and scattering from the nanoparticle can be greatly enhanced via the coupling of the incident radiation with the collective motion of electrons in metal. However, the surface pl...

In this thesis, a literature review of hybrid solar-fossil fuel power generation is first given with an emphasis on system integration and evaluation. Hybrid systems are defined as those which use solar energy and fuel simultaneously, thus excluding the viable alternative of solar thermal plants which use fossil fuels as backup. The review is divided into three main sections: performance metric...

Parabolic-trough solar collector fields are large-scale systems, so the application of centralized optimization-based control methods to these systems is often not suitable for real-time control. As such, this paper formulates a novel coalitional approach as an appropriate alternative scheme. The key idea split overall field into smaller subsystems, each them governed by local controller. Then,...

In order to effectually improve the performance of parabolic trough solar collector system and homogenize temperature distribution on absorber tube, an innovative convergent-divergent tube was designed as PTR. The finite volume method (FVM) Monte Carlo ray tracing (MCRT) are combined simulate heat transfer process in collector. average relative error between numerical results experimental condu...
