Comparison of unsteady incompressible micropolar and nanofluid flow with heat transfer applications

This chapter deals the unsteady magnetohydrodynamic flow of a Au-blood micropolar nanofluid containing slip effects over an inclined stretching sheet. Micropolar fluid is considered as blood (basefluid) and Au (gold) as nanoparticles. Joule heating and thermal radiation are taken into account. The partial differential equations are converted into ordinary differential equations by using appropriate similarity transformations and then solved numerically by using bvp4c MATLAB software. The results are compared with the existing results, and are in good agreement. The impacts of the parameters on dimensionless velocity, microrotation, temperature, and the heat transfer rate of Au-blood nanofluid are investigated in detail. Furthermore, with an increment of the Grashoff number and coupling parameter, the velocity of the fluid is increased. When the volume fraction rises, velocity and angular momentum are decreased and the thermal slip parameter is increased with an increase in the nanoparticle volume fraction.
