In this study, the magnetohydrodynamic pulsatile flow of a couple stress nanofluid in a channel has been discussed in
detail by adopting Buongiorno’s nanofluid model. The impacts of Brownian motion, thermophoresis, Ohmic heating,
viscous dissipation and chemical reaction on heat, and mass transfer of blood based nanofluid are considered. The
current concept is significant in the field of nano-drug supply, dynamics of physiological fluids, and biomedicines. The
governing partial differential equations are converted into a set of ODEs (ordinary differential equations) by employing a
perturbation scheme. The resulting non-dimensional system is numerically interpreted to determine the impact of various
emerging parameters on flow variables by utilizing the shooting technique with the support of the Runge-Kutta
procedure. The outcomes reveal that the temperature rises with the magnifying viscous dissipation, Brownian motion,
and thermophoresis parameters, whereas the opposite trend can be seen with an escalation in the couple stress parameter.
Heat transfer rate is an accelerating function of Brownian motion and thermophoresis parameters while it is a
decelerating function of couple stress parameter and Hartmann number. Mass transfer rate declines with increasing
values of thermophoresis parameter and Lewis number.
