Entropy generation analysis in electroosmotic peristaltic flow of blood-based Jeffrey nanofluid under heat source/sink effects

Here, the electroosmotically aided peristaltic pumping of a blood-based nanofluid flowing under the impact of heat source/sink and viscous dissipation through an asymmetric channel is investigated. The Jeffrey fluid model is adopted for predicting non-Newtonian characteristics of blood. The analysis is conducted under the lubrication theory approximation and the Debye–Hückel linearization principle for electric potential. The mathematical model linearized under the linearization approaches is solved to obtain the analytical solution for the flow characteristics using Mathematica, which is also utilized to generate graphical representations of the results. Results reveal that assisting electroosmotic forces enhance velocity, and reduce pressure gradients, while viscoelastic effects increase resistance to flow. Entropy generation and Bejan number distributions are also analyzed to assess thermodynamic irreversibility and efficiency. This study contributes to the design and optimization of microfluidic transport systems in biomedical, chemical, and engineering applications under electrokinetic and peristaltic influences.
