Modified starch, derivatives of cellulose and sodium alginate are shear thinning fluids which can be analyzed using hyperbolic tangent model as these fluids can be used as natural thickeners in the ink. Thus, the present article's intent is to study the flow conduct of hyperbolic tangent nanofluid in microchannel situated horizontally. The impact of viscous dissipation and magnetic field is recorded. The suction‐ injection is promoted at the walls of the microchannel. Two imperative slip mechanisms like Brownian motion and thermophoresis are accounted for the study. Entropy scrutiny is carried out for system effectiveness. To simplify the non‐linear equations certain non‐dimensional variables are used. The obtained mathematical formulations are solved using an efficient problem‐solving operation namely Runge–Kutta–Fehlberg 4–5th order method. The parameters attained are studied using graphical illustrations. The findings of this article comprehend that on enlarging Weissenberg number, flow field declines at the bottom wall and levitates at the top wall and the material power law parameter magnifies the velocity distribution. Entropy generated is maximum at top wall and minimum at the bottom wall for the Brownian motion parameter but the reverse manner is attained for thermophoresis parameter. Incorporating porous media to the microchannel for the flow of shear thinning fluid is useful in cell engineering, spotting particles and filtering.

“…Almeida et al, [37] explored the intricate characteristics of micropolar fluids in micro channels considering the effects of Brownian motion and thermophoresis. Madhura and Babitha [38] conducted a study to examine the impact of nonlinear thermal radiation on the unsteady boundary layer flow of a micropolar Carreau nanofluid along a stretching sheet in the presence of Brownian motion and thermophoresis. Their investigation utilized the finite difference method to analyse the problem.…”

The objective of this paper is to analyze the impact of thermophoresis parameter, Brownian motion, velocity ratio parameter, similarity radius of the slim needle, magnetic parameter, Prandtl number and thermal radiation on the steady state, laminar, MHD hybrid nanofluid composed of MgO-Ag/H2O flowing along a horizontal hot thin needle. To achieve this, the BVP-5C shooting technique is employed through MATLAB to solve the transformed nonlinear ODEs governing the fluid flow. This study investigates the impact of non-dimensional parameters on the flow velocity, temperature and concentration profiles within the hybrid nanofluid. The effects of skin friction, local Nusselt number and Sherwood number are demonstrated through the use of tables. The observation reveals that elevating the thermophoresis parameter results in a simultaneous reduction in the temperature and concentration profiles, while an opposite behavior is observed for Brownian motion. The magnetic parameter and thermal radiation values result in a rising temperature profile, while the trend is reversed for the velocity ratio parameter, Prandtl number and Schmidt number. The Nusselt number demonstrates an upward trend with higher values of thermophoresis parameter, velocity ratio parameter and thermal radiation. Further, Sherwood number experiences an increase with greater values of Brownian motion and magnetic parameter but it displays a contrasting pattern for thermophoresis, velocity ratio parameter and thermal radiation parameter. Validation of this model with existing data has been excellent.
