In this analysis, the thermal and flow properties of modified hybrid nanofluids (MNFs) have been investigated under the effects of electroosmosis and homogeneous-heterogeneous chemical reactions. Three types of nanoparticles of Cu, CuO, and Al2O3 are utilized to monitor the performance of the MNFs with water as a working liquid. The determination of the heating phenomenon is explored by incorporating the effects of NPs shape, temperature reliant viscosity, Joule heating, heat generation/absorption and viscous dissipation. In this exploration, equal diffusion factors for the auto catalyst and reactants are assumed. The model formulation contains a highly non-linear PDE system, which is converted to ODEs under physical assumptions with lubrication and Debye–Huckel. The solution treatment involves the Homotopy perturbation method for solving the governing differential equations is used. A major outcome discloses that an addition in heterogeneous reaction parameter aids in enhancing the concentration profile. In a result, the temperature curve decreases at increasing volume fraction of the NPs. Modified hybrid NFs have higher heat transfer rate as compared to base H20, or ordinary Al2O3–H20 and hybrid Cu + Al2O3–H20 NFs. Pressure gradient decreases by improving electroosmotic parameter. Further a comparison between analytically (HPM) and numerical results (NDSolve) show that both results are in good agreement.

The non‐Newtonian fluids have abundant implications in versatile fields of chemical, mechanical, and biological engineering. Furthermore, the non‐Newtonian fluids flowing through the porous medium are very useful in petroleum and industrial engineering. Heat transport analysis with radiation has major appliances in fusion reactors, heat exchangers, solar energy, aircrafts engines, turbine cooling, and many others. Having all these important appliances in view, the present study is focused on the heat transfer analysis of an incompressible two‐dimensional viscoelastic magnetohydrodynamic Maxwell non‐Newtonian liquid flow in a porous space. The magnetic field is uniformly applied tangential to the flow direction and the lower‐channel wall is heated by induction as a consequence of the Lorentz force. The effect of thermal radiation is taken to foresee the physical occurrence of heat kinetics from an applied point of view. Similarity transformation is considered in reducing the governing partial differential equations into ordinary differential equations and a numerical solution is computed using the shooting technique. The results obtained are compared with the published literature. The effects of flow quantities are illustrated graphically and analyzed with physical meaning. In view of engineering applications, the effects of Reynolds on skin friction coefficient and rate of heat transfer are presented.

The present study employs irreversibility analysis for the peristaltic movement of a nanofluid. The viscosity of the nanofluid is assumed to vary with the local concentration of colloidal particles. Impacts of thermophoresis, magnetic field, Brownian motion, Ohmic heating, viscous dissipation, and buoyant forces are considered in the flow analysis. Equations representing the flow and heat/mass transfer are prepared by employing Buongiorno's model for nanofluids. The lubrication approach is used to simplify the governing equations. The resulting system of differential equations is numerically solved with the aid of NDSolve in Mathematica. Results for entropy generation, Bejan number, velocity, temperature, and concentration are graphically presented. Outcomes show that entropy generation and temperature reduce by increasing the values of viscosity parameter. By increasing buoyancy forces due to temperature difference, the entropy generation increases, whereas the concentration profile shows a decreasing behavior. Maximum velocity reduces with an increment in the Hartman number.
