This work investigates the Ohmic heating, nonuniform heat generation, and Hall effects with Cattaneo-Christov model (CCM) on flow transfer of power-low non-Newtonian fluids (NNFs) past stretching surface embedded in a porous medium. Runge-Kutta method is used to solve non-linear ODEs numerically using shooting procedure. We study for power law values 0.7 1.2, respectively. Innovation this lies studying effect currents presence buoyancy force an irregular source slip NNFs moving through Darcy Varying velocities, frictional forces, Nusselt numbers are examined. Resulting entropy also examined computational problem investigation. Model-simulated results suggested that various factors play critical role constructing thermal systems. It asserted parameter, mixed convection Biot numbers, relaxation time improve transference rates by directly affecting fluid molecules temperature.
