“…Kumar et al 30 mentioned the consequences of the thermal radiations on an unstable convective flow for nanofluids directed by linear movement of the involved vertical plate and outlined that the temperature profile of nanofluid improves by enhancing the thermal‐radiation parameter. In addition, corresponding to the given context, it is quite worth mentioning similar investigations demonstrated in many studies 31–43 …”

The given investigation concerns the study of non‐Newtonian Oldroyd‐B fluid flow across a permeable surface along with nonlinear thermal radiation, chemical reactions, and heat sources. Equations modified are thus numerically evaluated by employing bvp4c‐technique. Obtained outcomes are exhibited graphically. Pictorial notations are used to investigate the consequences of necessary parameters of velocity, energy, and mass. Acquired outcomes provide promising agreement with already established consequences provided in the open literature. The obtained results guided that magnetic field parameter (), porosity parameter (), Deborah number reduce momentum boundary layer thickness, furthermore, growth in the relevant Deborah number improves the corresponding momentum boundary layer.

“…They reported a significant enhancement in heat transfer rate with a corresponding rise in the Hartmann number. Kanimozhi et al [9] evaluated the impact of coupled buoyancy and thermocapillary driven convection in a cylindrical porous annulus saturated with water based Ag-MgO hybrid nanofluid along with viscous dissipation effects. At varying levels of random motion of nanoparticles, a higher volume percentage resulted in a decreased heat transmission rate.…”

Sodium-alginate (SA) based nanofluids represent a new generation of fluids with improved performances in terms of heat transfer. This work examines the influence of the nanoparticle shape on a non-Newtonian viscoplastic Cu-nanofluid pertaining to this category. In particular, a stretching/shrinking sheet subjected to a transverse magnetic field is considered. The proposed Cu-nanofluid consists of four different nanoparticles having different shapes, namely bricks, cylinders, platelets, and blades dispersed in a mixture of sodium alginate with Prandtl number Pr = 6.45. Suitable similarity transformations are employed to reduce non-linear PDEs into a system of ODEs and these equations and related boundary conditions are solved numerically by means of a Runge-Kutta-Fehlberg (RKF) method. Moreover, analytical solutions are obtained through the application of a MAPLE built-in differential equation solver (Dsolve). The behavior of prominent parameters against velocity and temperature is analyzed. It is found that the temperature increases for all shapes of nanoparticles with the viscoplastic parameter and the Eckert number.
