Abstract
The present article investigates the steady 3D flow of a Carreau liquid influenced by bidirectional stretching surface. In the presence of Cattaneo–Christov double diffusion with temperature-dependent thermal conductivity, the heat and mass transfer mechanisms have been scrutinized. The alteration of nonlinear PDEs to nonlinear ODEs is equipped via apposite conversions and then resolved numerically by means of bvp4c scheme. The graphical assessment is exposed to portray the essential features of somatic parameters on Carreau liquid temperature and concentration distributions. This study indicates that the variable conductivity parameter enhances the liquid temperature, while the thermal relaxation time parameter and Prandtl number are diminishing functions of temperature field. Furthermore, our results illustrate that the concentration relaxation time parameter and Schmidt number diminish the concentration field. The assertion of present exploration is asserted by emergent assessment with former outcomes vacant in prose, which sets a benchmark for execution of computational methodology. Moreover, graphical assessment is also vacant for two altered techniques, namely analytical (HAM) and numerical (bvp4c).
