Abstract:

The aim of this study is to enhance the operating thermal efficiency of solar aircraft through the use of solar thermal radiation and ternary hybrid nanofluids (THNF). The study inspects the convective thermal transfer in wings of solar aircraft using a noble innovative THNF which consists of has Copper (Cu), SiO2  Silicon dioxide, Zirconium dioxide (Zr02) nanoparticles and in Propylene glycol (C3H8O2) as the basic fluid. The model used to analyze the problem uses a parabolic trough solar collector (PTSC) to model the solar thermal radiation and makes use of Cattaneo-Christov heat flux model in order to account for the non-Fourier heat conduction phenomena. Wavelets and Gegenbauer wavelets methods was uses to solve the system of ODEs. The study results display that the improvement of thermal transport via THNF is due to the advanced thermal conductivity of the nanoparticles and elevated capability of the THNF to collect and absorb solar power energy.  The Cattaneo-Christov model offers a better representation of heat flux with the incorporation of thermal time delay resulting in the enhanced prediction of thermal behavior in the aircraft wings. Also, PTSC is significantly beneficial in the enhancement of the thermal management procedure of the solar energy harvesting process.
