The present study analyzes the peristaltic mechanism of Casson hybrid nanofluid flow through a compliant channel under the combined influences of electromagnetohydrodynamic effects, Hall current, wall properties, and thermal radiation. The model incorporates velocity slip and couples convective boundary conditions, capturing microscale transport phenomena. The governing nonlinear equations describing momentum, heat, and mass transport are solved analytically using the homotopy perturbation method, ensuring accurate approximation of the coupled flow behavior. Furthermore, the effects of key physical parameters on velocity, temperature, and concentration fields are examined through detailed graphical analyses carried out in MATLAB R2024b. The results indicate that the motion of particles enhances fluid mixing, thermophoresis increases thermal gradients, and activation energy decreases the heat, concentration, and flow fields. The analysis of entropy generation reveals that thermal and viscous irreversibilities are the primary contributors to variation in gold and silver nanoparticle species volume fraction. In contrast, the Bejan number indicated the different transition regimes. The results confirm the importance of nanoparticle pumping in biomedicine and microfluidics. Presenting the new research has unified the theoretical and practical aspects of transport in the mentioned area and opened new ways for the optimization of peristaltic pumping systems in modern technologies.
