Insights into the thermal attributes of sodium alginate (NaC₆H₇O₆) based nanofluids in a three-dimensional rotating frame: A comparative case study

The present work distinguishes the thermal attributes of zirconium oxide (ZrO₂) and single wall-carbon nanotubes (SWCNTs) in a three dimensional rotating frame under the magnetic field environment. Sodium alginate (NaC₆H₇O₆) is assumed to be the base fluid. The slippage and convective conditions on boundary have also been incorporated. The analysis comprehends, comparatively, features of both SWCNTs-NaC₆H₇O₆ and ZrO₂–NaC₆H₇O₆ nanofluids. The amalgamation of nanomaterial SWCNTs-ZrO₂ in sodium alginate builds up the thermal characteristics. An algorithmic approach deals with the approximate solutions of the problem. The numerical algorithm is mainly based on order reduction and central difference discretization. A comparison, in limiting case, appraises the proficiency of the code. The outcomes are physically and numerically interpreted via graphical and tabular representations against the prime parameters. The nano-composition of SWCNTs-ZrO₂ convincingly improves and embellishes the heat transport rate. It has been revealed from the results that higher the microrotation parameter Ω₀, higher will be the thermal boundary layer thickness in both cases of nanofluids such as SWCNTs/NaC₆H₇O₆ and ZrO₂/NaC₆H₇O₆. A sensible judgment of the outcomes discloses that SWCNTs possess, comparatively, better heat transfer features than zirconium oxide.
