The hydromagnetic free convective flow model of a hybrid nanofluid of Newtonian properties has been studied in this work by considering the effects of radiation, heat generation, viscous dissipation, and activation energy through a porous medium in a vertical channel. The governing equations of the flow model are converted from partial differential equations to ordinary differential equations and subsequently solved analytically using the multiple-parameter perturbation approach method. The graphical representation of the significant findings of the parameters is achieved via the utilization of MATLAB software. The research findings indicate that an increase in the Darcy (Da) parameter results in a substantial elevation in the fluid velocity as it traverses the porous material within the upward channel. More specifically, the increase in the heat-generating parameter indicates a progressive rise in the fluid's velocity and temperature. Moreover, an evident escalation in the temperature and velocity distributions of the fluid is observed as the activation energy rises. The presence of activation energy resulted in a more significant improvement in the temperature and velocity distributions for the parameters R, Q, Ha, and Da compared to the absence of activation energy.
