Coupled Dufour and Soret Effects on Hybrid Nanofluid Flow through Gyrating Channel Subject to Chemically Reactive Arrhenius Activation Energy

Arshad Khan*, Taza Gul, Ishtiaq Ali

This study explores the magnetohydrodynamic fluid flow through two rotating plates subject to the impact of microorganisms. The nanoparticles of copper and alumina are mixed with water for formulating hybrid nanofluid with new combination (Cu+Al₂O₃+H₂O). This new combination augments the thermal conductivity of pure fluid. The flow is influenced by the coupled effects of Dufour and Soret diffusion. The joined effects of chemically reactive activation energy have also been incorporated in the mass transportation equation. A constant magnetic field has been employed to the flow field with strength B₀ in normal direction to the plates. The equations that controlled fluid flow have been transferred to dimension-free form by implementing suitable set of variables. The influence of the different factors has been examined theoretically by employing the graphical view of different flow profiles. It has concluded in this work that linear velocity has declined by augmentation in magnetic factor and rotational parameter whereas these factors have enhanced microrotational profiles of fluid. Higher values of radiation parameter, Dufour number and volumetric fractions have augmented fluid’s thermal profiles. Concentration of fluid has been retarded with upsurge in Soret number and chemical reaction parameter whereas growth in activation energy parameter has supported the upsurge in concentration. Rate of motile microorganisms has retarded by upsurge in the values of Lewis and Peclet numbers.
