Chemical reaction and thermal characteristiecs of Maxwell nanofluid flow-through solar collector as a potential solar energy cooling application: A modified Buongiorno's model
Solar collectors absorb solar radiation at the focus of solar concentrating systems as heat energy which is further transferred to nanofluid. Entropy creation in Maxwell nanofluid flow over an infinite horizontal surface of a porous media is the subject of the current investigation. A non-linear stretching surface then induces a parabolic trough solar collector (PTSC) flow. The thermal boundary layer is studied using a modified version of Buongiorno's Model. As a result, the PDEs, which encompass the physical aspects of the issue, must be transformed into solvable and boundary-constrained ODEs. By using a proper similarity transformation, boundary conditions and partial differential expressions are reduced to a set of non-linear ordinary differential equations. The Keller box method is used to find approximate solutions to ODEs. Tests are carried out on a nanofluid known as Copper-engine oil (Cu-EO). The Nusselt number was lowered, but the skin friction coefficient was increased as a result of a substantial magnetic parameter. In addition, Reynolds number and Brinkman number are used to measure fluctuations in viscosity, and, as a result, entropy variations throughout the domain are increased. Temperature decreased due to chemical reaction and Schmidt number, while thermal radiation increased skin friction and Nusselt. According to the current analysis, the heat collector has enhanced PTSC with Maxwell nanofluid.
期刊介绍:
Energy & Environment is an interdisciplinary journal inviting energy policy analysts, natural scientists and engineers, as well as lawyers and economists to contribute to mutual understanding and learning, believing that better communication between experts will enhance the quality of policy, advance social well-being and help to reduce conflict. The journal encourages dialogue between the social sciences as energy demand and supply are observed and analysed with reference to politics of policy-making and implementation. The rapidly evolving social and environmental impacts of energy supply, transport, production and use at all levels require contribution from many disciplines if policy is to be effective. In particular E & E invite contributions from the study of policy delivery, ultimately more important than policy formation. The geopolitics of energy are also important, as are the impacts of environmental regulations and advancing technologies on national and local politics, and even global energy politics. Energy & Environment is a forum for constructive, professional information sharing, as well as debate across disciplines and professions, including the financial sector. Mathematical articles are outside the scope of Energy & Environment. The broader policy implications of submitted research should be addressed and environmental implications, not just emission quantities, be discussed with reference to scientific assumptions. This applies especially to technical papers based on arguments suggested by other disciplines, funding bodies or directly by policy-makers.
