Investigation of thermal radiation and chemical reaction impacts on Carreau-Casson nanofluid flow across a stretching sheet: A solar aircraft application

New advances in nanotechnology are setting up new potential for energy conversion and temperature management, which has significantly improved solar aircraft performance. Considering this application, the present work investigates the impact of quadratic radiation on Carreau-Casson nanofluid across a porous stretched sheet in the presence/absence of slip condition. The governing equations that capture the entire variety of these effects result in highly sophisticated partial differential equations and then the bvp-4c numerical approach is utilized to resolve difficult boundary value problems. The consequences of the various factors over respective profiles concerning the problem are analyzed and displayed visually. The current study's main outcomes reveal that larger values of Weissenberg number, Casson, and porosity decrease fluid flow velocity. Improved temperature profile was achieved for elevated values of radiation, Brownian and Thermophoretic parameters. Further, concentration profile drops for increasing values of Thermophoresis. The quantitative results reveal 7.84% rise in skin friction for growing porosity parameter while larger casson and Weissenberg number cut it to 7.24% and 7.53% with less impact on heat and mass transfer rates. On the hand, upsurge values of brownian and thermophoretic parameter improves heat transfer to 7.56% and 2.36% respectively whereas thermal radiation restrains heat and mass transfer to −0.17% and −0.24% respectively. Also, we have obtained an optimal correlation when we compare the present findings to the previously reported outcomes.
