Comparative study on hybrid nanofluid flow of Ag–CuO/H₂O over a curved stretching surface with Soret and Dufour effects

Abstract

The purpose of the study is to discuss the comparison of the linear and nonlinear stretching sheets on the heat transfer over a curved surface spiraling in a circle with radial distance R. Additionally the consequences of Soret-Dufour in the presence of injection velocity and heat source/sink are investigated in the article.Silver and Copper Oxide are taken as hybrid nanoparticles with water as foundation fluid. Leading equations are converted to nonlinear ordinary differential equations taking some relevant transformations and solved with the combination of the shooting method and RK-4th order method. MAPLE software is used to plot graphs and numerical charts. Flow features are examined for different pertinent parameters. Physical quantities like Sherwood number, Nusselt number, and so forth, are evaluated numerically for different nondimensional numbers. The result substantiates that improving the Dufour number boost the fluid flow and fluid temperature but the opposite behavior is seen in the concentration profile. It is observed that a linearly stretching sheet gives better fluid behaviors compared to nonlinear stretching sheet.

Multieffect bioconvective transport of oxytactic microorganisms with thermal radiation, Lorentz force, heat source, and chemical reaction over a flexible cylinder

“…Slip factor and activation energy have an impact on the Sherwood number and velocity profiles, as observed by Naz et al, 34 Bodduna et al, 35 and Ali et al 36 The complex interactions between these variables and how they affect the generation of entropy are of utmost importance. Sharma et al [37][38][39] and Rao et al 40 studied hybrid nanofluid flow with the Soret and Dufour effect, squeezing motion analysis and diffusion thermo effect and investigated that elevated radiative heat and the presence of a heat source contributes to the elevation of nanofluid temperature, while an increase in the thermal radiation parameter corresponds to an augmentation in the Nusselt number.…”

Heat and Mass Transformation of Casson Hybrid Nanofluid (MoS2 + ZnO) Based on Engine Oil over a Stretched Wall with Chemical Reaction and Thermo-Diffusion Effect

“…Two distinct types of fluids, specifically, hybrid nanofluid (Cu-Al 2 O 3 /Water) and nanofluid (Cu/Water), were utilized in the investigation of movement past a stretching sheet. Ram Prakash Sharma et al's [12] study compared the effects of the thermal properties of curved surfaces spiralling in a circle at different distances from a centre using linear and nonlinear stretching sheets. The Soret-Dufour phenomenon is also examined in relation to the injection velocity and heat source/sink.…”
