The present model intends to study the electroosmotically augmented peristaltic flow of blood-based nanofluid through an asymmetrical channel. The Buongiorno’s model is used to study the effects of Brownian motion and thermophoresis on various features of peristaltic motion. The mathematical equations governing the problem incorporate considerations such as electroosmosis, viscous dissipation, magnetic field, chemical reaction, porous medium, and heat generation/absorption. In addition, blood is considered a non-Newtonian fluid suitable for nanoscale and microscale transport. To simplify the flow equations, the lubrication and the Debye–Hückel linearization approximations are used. A built-in numerical technique enables a graphical representation of relevant metrics on physiological flow parameters. The investigation reveals that the magnetohydrodynamic effect generates a Lorentz retarded force that slows blood movement. The increasing values of Darcy number amplify the pressure gradient. However, an increase in Casson parameter reduces the skin friction coefficient. Entropy rate can be controlled through radiation parameter. It is also seen that temperature of Fe 3 O 4 –blood nanofluid has an increasing effect on electroosmotic parameter. Further, a growth in chemical reaction parameter causes an enlargement in the concentration field. Such an analysis enables the flow of biological liquids in arteries and vessels for the transport of blood circulation, nutrients, transport of heat, oxygen, and other nutrients into the body.
