This investigation involves a comprehensive analysis of the flow characteristics, including velocity profiles, pressure distribution, temperature distribution and streamlines of an electroosmotic induced peristaltic flow of a nanofluid in a porous channel. The hybrid nanofluid's influence on heat transfer and convective cooling is studied in detail. The research incorporates numerical simulations to model the coupled effects of electroosmosis and peristalsis, providing insights into the synergistic impact on fluid transport and thermal performance. Results indicate that the hybrid nanofluid exhibits unique thermal and rheological properties. We found that stronger electric fields enhance heat transfer and higher Soret number indicates stronger thermal gradients. The findings contribute to the understanding of complex fluid dynamics in microchannels, offering valuable insights for designing advanced systems for thermal and transport properties in microfluidic devices, drug delivery, and biomedical engineering. It is seen that with the increase in Biviscosity parameter, the velocity profile rises 5%. Further it is seen that rising 2% in Biviscosity parameter ξ, the temperature profile rise 2.5%.
