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.
