This computational study elucidates electromagnetic field effects on peristaltic transport of nanofluids in microfluidic channels using CFD modeling. The feasibility of electroosmotic micropumping for biomedical applications has garnered interest. However, the unique properties and motion of nanofluids warrant investigation. This work examines the impact on peristaltic heat and mass transfer in a non-uniform microchannel geometry incorporating electroosmosis. By explicitly accounting for electroosmotic factors, the coupled PDE system is solved to obtain concentration, temperature and velocity fields. While the electromagnetic simulations prove essential, a key focus lies on electroosmosis phenomena. Effects on parameters including skin friction, Nusselt and Sherwood numbers are analyzed for Casson and Newtonian nanofluids. Visual probing of trapping events further reveals the role of electroosmosis. Overall, this computational approach provides insights into the multifaceted interplay between peristalsis, nanofluids and electroosmotic flows under electromagnetic forces in microfluidic configurations. The perspectives gained at intersection of CFD, biomedical and nanotechnology domains can facilitate optimized designs of electroosmosis-driven biomedical microdevices.
