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.
