| description | This study reports Darcy-Forchheimer stagnated flow confined by elongating surface. Nanofluid dynamics is scrutinized through Brownian movement and thermophoresis. Flow formulation features non-Newtonian rate type (Maxwell) material. Transportation expressions (i.e., energy and concentration) are modeled under varying conductivity, generalized heat-mass transference (i.e., Cattaneo-Christov (CC) dual diffusion theories) and varying diffusivity. The approach utilized in this investigation involves initially deriving the nonlinear PDEs (partial differential expressions) that govern the dynamics of flow along with heat-mass transference. Subsequently, these PDEs are transmuted into their corresponding ODEs (ordinary differential expressions) utilizing similarity variables. To compute these resulting ordinary differential expressions, a homotopic scheme is deployed. The solutions obtained for these ordinary differential expressions impart insights into deviations in non-dimensional quantities. These outcomes are visually represented through graphs and subjected to an inclusive analysis. The analytical outcomes are authenticated with a previously available limiting case and found exceptional agreement, confirming the precision and consistency of deployed analytic scheme. It is noticed that escalating relaxation-time factors yield a decay in temperature along with nano-particles concentration while opposite characteristics are reported for varying conductivity and diffusivity factors. |
