Examining the movement of MHD hybrid nanofluid flows along linearly extending regions provides valuable insights for improving heat transfer efficiency. Many researchers have investigated various factors, such as Forchheimer number, porosity, radiation, aligned magnetic field and mixed convection, in context incorporating nanofluids into these flows. The existing literature lacks discussion on effect radiation absorption with parameter an flow a 3-D rotating Ag−CuO/H2O through expanded sheet. current research endeavours to address this gap offer particular factors. BVP-5C shooting scheme MATLAB is utilized solve system that governs nonlinear PDEs by converting them ODEs. influences dimensionless parameters, including (1 ≤ Q 2), number (0 Fr 9), porosity K 4), M α π/2), velocity x y-axes, temperature profile concentration distributions are discussed. Also, skin friction, mass rate impacts demonstrated traverse tables. Velocity both y-axes decreasing increases. As values rise, there corresponding decrease field. Greater leads increase nanofluid. Nusselt demonstrates upward trend when parameter, absorption, experience increase, whereas Sherwood exhibits contrary behaviour identical parameters. study compatibility 99.9% preceding across diverse stretching ratio parameter.
