Abstract:In this article, the Cattaneo-Christov heat flux model is implemented to study non-Fourier heat and mass transfer in the magnetohydrodynamic flow of an upper-convected Maxwell fluid over a permeable stretching sheet under a transverse constant magnetic field. Thermal radiation and chemical reaction effects are also considered. The nonlinear partial differential conservation equations for mass, momentum, energy, and species conservation are transformed with appropriate similarity variables into a system of coupled , highly nonlinear ordinary differential equations with appropriate boundary conditions. Numerical solutions have been presented for the influence of pertinent parameters on velocity components, temperature, and concentration profiles using the successive Taylor series linearization method (STSLM) utilizing Chebyshev interpolating polynomials and Gauss-Lobatto collocation. The effects of selected parameters on skin friction coefficient, Nusselt number, and Sherwood number are also presented with the help of tables. Verification of the STSLM solutions is achieved with existing published results demonstrating close agreement. Further validation of skin friction coefficient, Nusselt number , and Sherwood number values computed with STSLM is included using Mathematica software shooting quadrature.
