Flow of Oldroyd-B nanofluid in non-inertial frame inspired by Cattaneo-Christov theory

Abstract

In this study, the rotating flow of Oldroyd-B nanofluid fluid bounded by the stretching surface is examined using the Cattaneo-Christov theory. A significant perspective of this endeavor is to include the consequences of Buongiorno’s model of nanofluids because of their improved heat transport. The order analysis approach was adopted to present mathematical modeling of momentum and energy laws. Using flow similarities, the partial differential equations are transformed into ordinary differential equations. A well-known semi-analytical method called the homotopy analysis technique is used to construct the series solution of produced ordinary differential equations. To explore how different physical flow factors, affect the fluid velocity, temperature, and concentration, the graphical results are sketched. Our findings show that thermal and solutal relaxation factors have a diminishing effect on temperature and concentration distributions. Also, due to the incorporation of elastic effects, we discovered that the hydrodynamic boundary layer grows thinner. Further, the rotation parameter also reduces the thickness of the boundary layer.
