This inquiry examines the steady-state chemical reaction, thermal radiation, and MHD Casson nanofluid (Blood /copper (Cu)) buoyancy-driven Darcy Forchheimer flow over an inclined plate. PDEs are converted into nonlinear ODEs through the similarity method. The Runge-Kutta fourth-order approach is used to numerically solve these equations using Maple software. Velocity, Temperature, and concentration profiles have been studied about the effects of the magnetic field, porosity, buoyancy force parameter, velocity, temperature, concentration slips, thermal radiation, chemical reaction, thermophoresis, and Schmidt number.
