Purpose Studying the shear stress and pressure resulting on the walls of blood vessels, especially during high-pressure cases, which may lead to the explosion or rupture of these vessels, can also lead to the death of many patients. Therefore, it was necessary to try to control the shear and normal stresses on these veins through nanoparticles in the presence of some external forces, such as exposure to some electromagnetic shocks, to reduce the risk of high pressure and stress on those blood vessels. This study aims to examines the shear and normal stresses of electroosmotic-magnetized Sutterby Buongiorno’s nanofluid in a symmetric peristaltic channel with a moderate Reynolds number and curvature. The production of thermal radiation is also considered. Sutterby nanofluids equations of motion, energy equation, nanoparticles concentration, induced magnetic field and electric potential are calculated without approximation using small and long wavelengths with moderate Reynolds numbers. Design/methodology/approach The Adomian decomposition method solves the nonlinear partial differential equations with related boundary conditions. Graphs and tables show flow features and biophysical factors like shear and normal stresses. Findings This study found that when curvature and a moderate Reynolds number are present, the non-Newtonian Sutterby fluid raises shear stress across all domains due to velocity decay, resulting in high shear stress. Additionally, modest mobility increases shear stress across all channel domains. The Sutterby parameter causes fluid motion resistance, which results in low energy generation and a decrease in the temperature distribution. Originality/value Equations of motion, energy equation, nanoparticle concentration, induced magnetic field and electric potential for Sutterby nano-fluids are obtained without any approximation i.e. the authors take small and long wavelengths and also moderate Reynolds numbers.

This study investigates the forced convective flow in a horizontally extended parallel-plate channel filled with a sparsely packed, chemically inert porous medium under magnetohydrodynamic (MHD) effects. Utilizing the Forchheimer model to account for both viscous and inertial effects, the problem is formulated as a nonlinear boundary value problem and solved using the Differential Transformation Method (DTM). The key observations indicate that as the Darcy number increases, there is a decrease in flow velocity, eventually transitioning to plug flow at higher values. To investigate thermal characteristics, uniform Ohmic heating is employed, and the temperature distribution is determined using the steady-state thermal energy equation, which excludes axial conduction. The findings demonstrate that both the Darcy number and magnetohydrodynamic (MHD) effects have a substantial impact on the velocity and temperature profiles. The DTM solutions are validated against limiting cases in the literature and demonstrated good agreement. This study enhances the understanding of porous media and the effects of MHD on convective flow and thermal distribution, providing valuable insights for applications involving porous structures and electromagnetic fields.
