Implication of electromagnetohydrodynamic and heat transfer analysis in nanomaterial flow over a stretched surface: Applications in solar energy
Abstract
The limited availability of non-renewable energy resources, the need to protect ecosystems, and financial considerations create a powerful driving force for studying renewable energy and improving thermal energy systems. The utilization of solar radiation and nanofluids containing polyvinyl alcohol–water-based fluids with copper nanoparticles offers an opportunity to improve the efficiency of sustainable solar heating systems. Owing to its usage, this research examines the electromagnetohydrodynamic and thermal transfer of Jeffrey nanofluid flow over a stretchable surface by employing the influence of gyrotactic microorganisms on this flow. Additionally, the current research focused on creating an advanced numerical model that accurately exemplifies the flow and thermal properties of a parabolic trough solar collector (PTSC) installed on a solar plate to generate a continuous energy source. The unique aspect of our research lies in the integrated approach, combining EMHD, nanofluid flow, and stretchable surface technology to investigate the thermal performance of the coating. This innovative combination opens up new possibilities for efficient thermal management in solar energy applications. The effectiveness of thermal transport in PTSC is evaluated by investigating several factors such as the electric field parameter, solar radiation, exponential heat source, bioconvection Rayleigh, and diffusion parameter. This research utilizes invariant transformations to simplify partial differential equations into ordinary differential equations. These equations are then solved using the wavelets and the Chebyshev wavelets scheme (CWS) with the help of MATHEMATICA 11.3 software. The research outcomes revealed that an increase in the solar thermal radiation, and electric field parameters leads to a higher temperature distribution in concentrated solar power. Therefore, this research aims to improve industrial performance by increasing the efficiency of thermal power generation systems.
