Abstract
Researchers are looking into more effective ways to employ solar energy with hybrid nanofluids (HNF) due to growing industrial requirements and the desire to reduce electrical energy prices and usage. However, solar radiation is necessary for photovoltaic cells and solar-powered systems to operate effectively. Therefore, the combined effect of solar radiation and variable thermo-physical properties on Casson HNF flow through a porous plate with a modified magnetic field was considered in this study. The governing partial differential equations (PDEs) were converted to non-dimensional ordinary differential equations (ODEs) by the application of similarity transformations. With the help of MATHEMATICA 11.3 software, the Chebyshev Collocation Method (CCM) was utilized to solve the ODEs in order to accomplish the model's objectives. The results showed that triple particle nanofluids (TPNFs) had a much higher thermal efficiency than both single (SPNFs) and double particle nanofluids (DPNFs). Also the results demonstrate that higher thermal radiation and magnetic parameter greatly improve heat dispersion, providing important information for maximizing the efficiency of solar power systems.
期刊介绍:
Nano-Structures & Nano-Objects is a new journal devoted to all aspects of the synthesis and the properties of this new flourishing domain. The journal is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. The journal is focused on the objects rather than on their applications. However, the research for new applications of original nano-structures & nano-objects in various fields such as nano-electronics, energy conversion, catalysis, drug delivery and nano-medicine is also welcome. The scope of Nano-Structures & Nano-Objects involves: -Metal and alloy nanoparticles with complex nanostructures such as shape control, core-shell and dumbells -Oxide nanoparticles and nanostructures, with complex oxide/metal, oxide/surface and oxide /organic interfaces -Inorganic semi-conducting nanoparticles (quantum dots) with an emphasis on new phases, structures, shapes and complexity -Nanostructures involving molecular inorganic species such as nanoparticles of coordination compounds, molecular magnets, spin transition nanoparticles etc. or organic nano-objects, in particular for molecular electronics -Nanostructured materials such as nano-MOFs and nano-zeolites -Hetero-junctions between molecules and nano-objects, between different nano-objects & nanostructures or between nano-objects & nanostructures and surfaces -Methods of characterization specific of the nano size or adapted for the nano size such as X-ray and neutron scattering, light scattering, NMR, Raman, Plasmonics, near field microscopies, various TEM and SEM techniques, magnetic studies, etc .
