Abstract : This study analyzes the Darcy-Forchheimer flow of an incompressible, chemically reactive Maxwell nanofluid over a radiative porous stretching surface, considering Cattaneo–Christov heat flux, activation energy, and motile microorganisms. A unified model is formulated to capture momentum, heat, solute, and microorganism transport under non-Fourier heat conduction. Similarity transformations reduce the governing equations to nonlinear ordinary differential equations solved in MATLAB using bvp4c. Results show thermal and solutal Grashof numbers enhance velocity, while Forchheimer resistance suppresses it. Radiation and heat generation raise temperature, and higher Peclet and Lewis numbers reduce solute and microorganism densities. Skin-friction, Nusselt, Sherwood, and motile densities quantify wall transport performance.
