Abstract

The effects of chemical reaction and radiative heat flux in nonlinear mixed thermo-solutal
convection flow of a viscoelastic nanoliquid from a stretchable surface are investigated theoretically.
Newtonian heating is also considered. The UCM (upper convected Maxwell) model is deployed to represent
non–Newtonian characteristics. The model also includes the influence of thermal radiation which is
simulated via an algebraic flux model. Buongiorno’s two-component nanofluid model is implemented for
thermophorestic and Brownian motion effects. Convective thermal and solutal boundary conditions are
utilized to provide a more comprehensive evaluation of temperature and concentration distributions.
Dimensionless equations are used to create the flow model by utilizing the appropriate parameters. The
computed models are presented through a convergent homotopic analysis method (HAM) approach with
the help of Mathematica (12) symbolic software. Authentication of the HAM solutions with special cases
from the literature is presented. The impact of various thermophysical, nanoscale and rheological
parameters on transport characteristics is visualized graphically and interpreted in detail. Temperatures are
strongly enhanced with Brownian motion and thermophoresis parameter. Velocity is boosted with
increment in Deborah viscoelastic number and mixed convection parameter and hydrodynamic boundary
layer thickness is reduced. Stronger generative chemical reaction enhances concentration magnitudes
whereas an increment in destructive chemical reaction reduces them and also depletes the concentration
boundary layer thickness. Temperature and concentration are also strongly modified by the conjugate
thermal and solutal parameters. Greater radiative flux also enhances thermal boundary layer thickness.
Increasing Schmidt number and Brownian motion parameter diminish the concentration values whereas
they elevate the Sherwood number magnitudes i.e. enhance nanoparticle mass transfer rate to the wall.
