The present work discloses the oscillating hydromagnetic blood-based couple stress nanofluid flow in between porous walls by the means of Buongiorno nanofluid model with Cattaneo–Christov heat flux. Joule heating, chemical reaction, viscous dissipation, and thermal radiation are accounted in this study. The flow governing equations are simplified by adopting the perturbation method and then solved by using the Runge–Kutta fourth-order approach with aid of a shooting procedure. The obtained results show that the temperature increases with the augmenting viscous dissipation, thermophoresis, thermal radiation, and Brownian motion, whereas the rising couple stress viscosity dwindling the temperature. Heat transfer rate is enhanced with the increment in thermophoresis and Brownian motion parameters whereas the reverse is true with the rise in couple stress and thermal relaxation parameters.
