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.
