Enhancement of solar absorption performance using TiN@SiCw plasmonic nanofluids for effective photo-thermal conversion: Numerical and experimental investigation

The current analysis tries to establish the hydrothermal characteristic for two hybrid nanofluids and a familiar nanofluid flow over a stretchable swirling cylinder. Graphene and Ferrous nanoparticles among present fluids water were appropriated by the affected flow. Moreover, the significant characteristics of aggressive space-dependent convective boundary conditions and heat source/sink were studied for flow and thermal mechanisms. Applicable comparison transformations were furnished to clarify those fluid equations for partial differential equations to ordinary differential equations. Every highest capable finite element method was enforced by clearing up consequent equations and boundary conditions. It’s extraordinary to the validity and reliability of the present numerical explanation in admirable accord with extant clear-cut solutions for the literature. Fluctuations by the confusions of swirling velocity, temperature, and axial velocity to certain related parameters are drawn over the design. The Nusselt number and twain components for skin friction coefficient values of more investigated elements are disclosed in the tables. The investigation finally confirms that nanoparticles were preferred to familiar fluids for improving heat transfer. Both the velocities are reduced for the magnetic flux, whereas temperature kept increasing. 

Hydrothermal features in the swirling flow of radiated graphene – Fe3O4 hybrid nanofluids through a rotating cylinder with exponential space-dependent heat generation

In the effort of mitigating global greenhouse gas emissions, renewables are crucial. Solar energy is a promising resource to be integrated in residential, commercial, and industrial applications. Flat plate solar collectors (FPSCs) typically harness solar energy. The goal of latest research trend is to enhance solar collector ability to capture irradiation. Phase change material (PCM) can maximize that due to their high latent storage capacity. However, common PCMs have a low thermal conductivity. Nanocomposites can enhance PCM thermal conductivity and thus improves overall system performance. The current review paper analyzes in details the integration of PCM and nanocomposite PCM in the FPSC. It provides thorough analysis of the system modeling. It also provides quantitative results of FPSC performance enhancement. Carbon based nanocomposites and metal foams have shown the greatest enhancement of PCM thermal conductivity. The optimum position for PCM integration is reported to be beneath the heat transfer fluid tubes. The incorporation of PCM guaranteed a longer time period of hot water supply from the collector. Major research contributions were critically assessed. In addition, the detailed review has highlighted scarce experiments done on nanocomposite PCM integration and a significant gap in the optimization analysis of such systems. Furthermore, there is a gap in the economical analysis that is needed for the widespread applications of the considered systems.
