Study on heat transfer aspects of solar aircraft wings for the case of Reiner-Philippoff hybrid nanofluid past a parabolic trough: Keller box method

Abstract

Solar energy is the major source of heat energy from the sun having immense utilization in technologies like photovoltaic cells, solar energy plates, solar street lights, solar water pumping, and so on. How to maximize the heat energy which is later on used as electrical energy for many purposes in solar aircraft is the hot topic of research in this decade. The current paper is about the study of entropy generation analysis and hybrid nano-solid particles impact on parabolic trough surface collector (PTSC) located inside the solar aircraft wings. homo/heterogeneous reactions have been taken. Non-Newtonian Reiner-Philippoff model along with porous medium and Darcy-Forchheimer effects have been taken into account for the present study. The heat transfer performance of the solar aircraft wings has been enhanced with the inclusion of effects like hybrid nanoparticles, thermal radiations, variable thermal conductivity, and viscous dissipation. By utilizing the proper conversions the demonstrated partial-differential equations are renovated into ordinary-differential formulas and tackled numerically with the utilization of well established numerical scheme termed as Keller-Box method. The impact of dimensionless sundry parameters on velocity, shear stress, temperature, homo/heterogeneous as well as surface drag and heat transfer rates are sketched through tables and figures. A positive variation in thermal radiation, thermal conductivity, and viscous dissipation effects enhances the heat transfer rate inside the solar aircraft wings.

Convective Heat Transport in Bidirectional Water Driven Hybrid Nanofluid Using Blade Shaped Cadmium Telluride and Graphite Nanoparticles under Electromagnetohydrodynamics Process

“…A mathematical formulation of these nanoparticles has been presented in the present analysis. Transports equations are initially modeled as PDEs and then transformed into nonlinear ODEs before computational inspection is made via the Keller-box procedure discussed in [38][39][40][41]. Numerical results of this contribution are helpful in heating/cooling processes, nano-drug delivery, power generation, and cancer therapy.…”

“…Additionally, influence of the Lorentz force is also incorporated in the mathematical model. Suitable mathematical relations have been used to transform the transport equations into dimensionless forms, and then, computer simulation is made via the Keller-Box method [53][54][55][56][57][58][59]. Finally, the foremost outcomes obtained through present numerical investigation are presented through various plots and tables.…”
