Here Darcy–Forchheimer 3D stretching flow of nanoliquid in the presence of convective condition and homogeneous–heterogeneous reactions is analyzed. Impacts of thermophoresis, Brownian diffusion and zero nanoparticles mass flux condition are considered. Adequate transformation procedure give rise to system in terms of ordinary differential equations. The governing mathematical system has been tackled by optimal homotopic technique. Graphical results have been presented for temperature and concentration dsitributions. Numerical benchmark is provided to study the values of skin friction coefficients and local Nusselt number. Skin friction coefficients are declared increasing functions of porosity and Forchheimer parameters. Furthermore the local Nusselt number is reduced for larger values of porosity and Forchheimer parameters. •Three-dimensional flow of nanofluid is modeled.•Flow saturating porous medium obeys Darcy–Forchheimer relation.•Nanofluid model consists of Brownian diffusion and thermophoresis.•Homogeneous and heterogeneous aspects are utilized.•Computations are made through optimal homotopy analysis method (OHAM).
