Abstract In this research, the three‐dimensional (3D) rotating /hybrid nanofluid (HNF) developed in Darcy–Forchheimer porous medium (DFPM) has been examined numerically across stretching/shrinking surface impact of convective heat transfer and source/sink effect. Moreover, Forchheimer, suction, MHD parameters on magnitudes reduced skin friction were using Tiwari‐Das model. The governing equations considered problem are transmuted into appropriate structure ordinary differential (ODEs) by employing linear similarity variables. resulting model ODEs is solved utilizing “three‐stage Labatto III‐A technique” provided “MATLAB software's” bvp4c solver. addition, to make evaluations, current numerical results compared with those from previous studies. Dual branches created ODE governance system. With aid stability analysis, a single stable branch identified. Reduced both shown increase rate. outcomes demonstrated that number dependent parameter ranges for porosity, magnetic given value rotation. temperature profile enhanced as increased amount source strength. obtained specified assortments related parameters. when solid volume copper was improved, strength intensified toward Forchheimer declined suction effects branches. Consequently, findings demonstrate duality occurs , but no fluid flow conceivable . Future research dual solutions HNFs may concentrate improved models, turbulent flows, biological applications, experimental validation. These developments will help build more efficient energy systems, industrial thermal management solutions.
