PULSATING HYDROMAGNETIC FLOW OF AU-BLOOD JEFFREY NANOFLUID IN A CHANNEL WITH JOULE HEATING AND VISCOUS DISSIPATION

This work studies the impact of pulsating hydromagnetic flow of Au-blood non-Newtonian nanofluid in a channel in the presence of Joule heating, viscous dissipation, and thermal radiation. Blood is taken as Jeffrey fluid (base fluid) and Au as nanoparticles. The Maxwell–Garnett model for thermal conductivity of nanofluid is considered. Flow is induced by pressure gradient. Analytical expressions for dimensionless flow variables are obtained by employing perturbation method. The influence of different parameters on velocity, temperature, and rate of heat transfer have been analyzed. The results reveal that the velocity of nanofluid is increased with increasing frequency parameter while it decreases with increasing magnetic field and volume fraction. The temperature of nanofluid is increased by increasing viscous dissipation. The rate of heat transfer rises with an increase in nanoparticle volume fraction and viscous dissipation. © 2022 by Begell House, Inc.
