Three-dimensional flow with Cattaneo–Christov double diffusion and homogeneous-heterogeneous reactions

Here three dimensional (3D) flow of second grade fluid has been studied in the presence of Cattaneo–Christov double diffusion and heterogeneous-homogeneous reactions. Flow is bounded by a bidirectional linear stretchable surface. Generalized versions of Fourier's and Fick's law through Cattaneo–Christov double diffusion are employed. Equal diffusion coefficients are considered for both autocatalyst and reactants. The conversion of partial differential system to nonlinear ordinary differential system has been done by employing appropriate transformations. The obtained nonlinear systems have been solved through the optimal homotopy analysis method (OHAM). Graphs have been displayed in order to examine how the velocities, temperature and concentration fields are affected by various pertinent parameters. Moreover the skin friction coefficients and heat and mass transfer rates have been computed and analyzed.
