Numerical Investigation of Mixed Convection Flow of Viscoelastic Nanofluid with Convective Conditions over an Exponentially Stretching Surface

Numerical analysis is performed for a ۳D incompressible viscoelastic nanofluid mixed convection flow model under the implications of convective boundary conditions towards an exponentially stretching sheet. The system that comprises differential equations of partial derivatives is remodeled into the system of differential equations via similarity transformations and then solved numerically through the Runge-Kutta-Fehlberg with shooting technique. The physical parameters, which emerge from the derived system are discussed in graphical formats. The significant outcomes of the current investigation are that the velocity field grows for a higher viscoelastic parameter while it reduces the fluid temperature. An increase in the mixed convection parameter diminishes the temperature and concentration. Further, the heat transfer rate is crumbled with the incremental values of the viscoelastic parameter. The obtained results show a better agreement with those available in the literature for limiting scenarios.
