Mixed Convection Over an Exponentially Stretching Surface with the Effect of Radiation and Reaction.

This study investigates the mixed convection on a vertically oriented exponentially stretching surface, considering the exponential distributions of velocity, concentration and temperature. The governing highly nonlinear partial differential equations (PDEs) are transmuted into highly nonlinear ordinary differential equations (ODEs) by considering appropriate similarity variables. The highly nonlinear differential equations are solved numerically using the Hermite wavelet method (HWM) in MATHEMATICA 12. The obtained results show excellent agreement with previous studies focusing on different special cases of the problem. A parametric analysis of the physical parameters is shown and illustrative numerical results are presented graphically. The analysis incorporates the radiation, chemical reaction and cross-diffusion effects. The interaction between radiation and chemical reaction is particularly relevant in high-temperature systems, such as combustion, industrial furnaces, photochemistry, polymerization and certain chemical reactions. The results indicate that an increase in radiation enhances the temperature profile in the momentum boundary layer. Higher reaction rate values lead to a decrease in the concentration profile, while an increase in the Dufour value results in increased velocity and temperature and decreased concentration. This research examines the combined heat and mass transfer in a vertical exponentially stretching surface with exponential variations in flow velocity, solute concentration, and temperature. The study takes into account the influences of thermal radiation, chemical reactions and Soret-Dufour effects. Considered, 2D laminar flow of an incompressible viscous fluid near an impermeable plane vertical wall stretching with velocity uw(x), temperature distribution Tw(x) and concentration distribution Cw(x) moving through a quiescent incompressible fluid of constant temperature T∞ and concentration C∞.
