Hybrid nanofluids can be designed to exhibit multiple functionalities, such as improved thermal conductivity, electrical conductivity, and magnetic properties. Magnetic hybrid nanofluids are gaining recognition in various mainstream applications, including heat transfer, solar systems, acoustic applications, and more. Further, hybrid nanofluids improve the thermal efficiency of radiators, efficiency of heating, ventilation, and air conditioning systems and drug delivery systems. Their notable advantage lies in their capacity to enhance the thermophysical properties of the constituent particles. Peristalsis of MHD hybrid nanomaterial [ ] in symmetric channel is emphasized. Darcy–Forchheimer law explores nonlinear nature of porous media. Effects of Joule heating and viscous dissipation are considered. The viscosity of fluid depends on temperature. The dimensionless system after invoking lubrication approach is analyzed numerically. Characteristics of prominent variables on the quantities under interest are examined. Comparative analysis of heat transfer rate of hybrid nanofluid and nanofluid are also discussed in detail. Heat transfer rate of system increases by increasing the quantity of nanomaterial in the fluid. Therefore, the temperature of the fluid decreases and the efficiency of the system increases.

The current article investigates the magnetohydrodynamic (MHD) radiative peristaltic flow of a couple stress nanoliquid in a symmetric channel. Thermally convective and zero mass flux conditions are imposed on flexible channel walls. Impacts of Joule heating and viscous dissipation are considered. Nanofluid model consists of important features Brownian motion and thermophoresis. First‐order chemical reaction is present in mass transportation. The resulting system of differential equations is numerically tackled after adopting large wavelength and low Reynolds number assumptions. Influences of pertinent variables of interest on concentration, temperature, coefficient of heat transfer, streamlines, skin friction coefficient, and Nusselt and Sherwood numbers are examined graphically. The findings of this study reveal that temperature enhances against Brownian motion and thermophoresis parameters, whereas it decays for radiation variable. Concentration of the fluid declines for a couple stress fluid variable. Further, the heat transfer coefficient shows increasing behavior for Eckert number.
