In the current investigation, hydromagnetic third grade pulsating nanofluid flow through a channel under the influence of Brownian motion, thermophoresis, radiative heat has been inspected. The influence of viscous dissipation, chemical reaction, and Ohmic heating is considered in the current investigation. The Buongiorno nanofluid model is implemented, and the analysis of entropy generation is carried out. The present investigation may be applicable in the fields of biomedical engineering, manufacturing industries as coolants, pressure surges, energy conservation, and nano-drug suspension in pharmaceuticals. The perturbation technique is employed on flow governing equations (partial differential equations (PDEs)) to convert into a set of ordinary differential equations (ODEs). The shooting process along with the support of Runge–Kutta fourth-order method is employed to solve the set of nonlinear ODEs. The impressions of dimensionless emerging physical parameters on pertinent flow variables are demonstrated by using graphical illustrations. The results portrayed that intensifying the Hartmann number, non-Newtonian, frequency, and material parameters decline the velocity of the nanofluid. Augmenting the Eckert number, Brownian motion, and thermophoresis parameter enhance the temperature whereas accelerating the radiation parameter and Hartmann number reduces the temperature. The nanoparticles concentration is enhanced for a rise in Brownian motion, while it decelerates for the higher values of Lewis number. The entropy and Bejan number are accelerated with the increment in radiation parameter. The heat and mass transfer rates are raised for augmenting the value of Brownian motion parameter.
