This study investigates the combined stability and sensitivity study of MHD radiative squeezed hybrid nanofluid flow between two parallel circular porous disks. Although numerous studies have examined magnetohydrodynamic (MHD) flows, thermal radiation effects, squeezed-flow configurations, and nanofluids in porous media, existing literature typically addresses these effects in isolation or in simplified combinations. Most prior works have focused on single-nanoparticle nanofluids, neglecting the enhanced thermo-physical behavior of hybrid nanofluids containing two different nanoparticles. The hybrid nanofluid comprises a base fluid embedded with two distinct nanoparticles, enhancing its thermal and flow properties. Several complex interactions including magnetic fields, thermal radiation, resistance in porous media, and squeezing effects influence the flow and thermal characteristics. A system of nonlinear partial differential equations is constructed and then converted into a dimensionless form through the application of similarity transformations. Subsequently, the dimensionless equations are solved using a power series method, and the resulting solutions are analyzed through the Hermite–Padé approximation scheme. A comparison between the current data and a published result has been made with a good agreement. The effect of flow parameters such as porosity parameter, squeeze number, Prandtl number, Eckert number, and radiation parameter on velocity and temperature fields is illustrated graphically. The skin friction coefficient and local heat transfer rate are also evaluated for the relevant physical parameters. The stability of the local heat transfer rate is examined through a bifurcation curve, which indicates that the lower branch represents a stable and physically realizable solution, while the upper branch corresponds to an unstable state. Sensitivity analysis is performed to measure the influence of key dimensionless parameters such as the squeeze number, porosity parameter, and radiation parameter on the local Nusselt number and the result of our model is significant. This work has potential applications in thermal management systems, energy devices, and advanced cooling technologies.
