Abstract

In the present study, a mathematical model is developed by combining the Tiwari-Das nanofluid
formulation with the Eringen micro-morphic model to simulate the thermo-solutal natural convection chemically
reacting micropolar nanofluid flow from a permeable stretching surface with non-uniform heat source/sink effects.
The transformed ordinary differential equation boundary value problem features linear momentum, angular
momentum, energy and species conservation boundary layer equations with appropriate boundary conditions.
This ninth order nonlinear system is solved with Runge-Kutta 45 Fehlberg method (Maple dsolve routine).
Several nanoparticles i.e., gold, and silver with aqueous base fluid are studied. The influence of the effect of the
emerging parameters on the velocity, angular velocity, temperature, nanoparticle concentration, skin friction,
couple stress, Nusselt number and Sherwood number distributions are visualized and tabulated. It is observed that
Increasing volume fraction decreases velocity whereas it elevates microrotation, temperature and nanoparticle
concentration. Nanoparticle concentrations are elevated for stronger destructive chemical reaction effect whereas
they are suppressed with constructive chemical reaction. With greater micropolar boundary condition parameter,
the velocity is elevated, microrotation but reduces temperature and thermal boundary layer thickness. Increasing
nanoparticle volume fraction enhances both skin friction and couple stress but marginally reduces the Nusselt
number. Finally, Au-water micropolar nanofluids achieve the highest skin friction and couple stress magnitudes,
then Ag-water and finally Cu-water. Validation of solutions with earlier non-reactive studies in the absence of
nanoparticle mass transfer are included.
