Thermal and electroosmotic transport of blood-copper/platinum nanofluid in a microfluidic vessel with entropy analysis

Electroosmotic flow through the biomechanical devices is efficient in targeting drug delivery of the human body parts related to the digestive and renal systems. In view of this, the present work is focused on the mathematical modeling of electroosmotic nanofluid transport driven by peristalsis. The impacts of magnetohydrodynamics, viscous dissipation, and thermal radiation on the intended stream have been considered. The resulting system of equations has been simplified with the lubrication approach and obtained the exact solutions for temperature, shear stress, velocity, trapping, and entropy generation. The impact of distinct physical parameters on nanofluid flow is graphically computed. It can be seen from the present study that the stronger electric field accelerates the entropy generation near the channel walls. A higher temperature is observed for blade nanoparticles presented in the base fluid. The stronger magnetic field reduces the size of the bolus. The higher velocities are noticed for the blood-platinum-based nanofluid as compared with blood-copper-based nanofluid.

Automated summary

This study focuses on the efficient drug delivery in the human body through electroosmotic flow targeting the digestive and renal systems. The mathematical modeling of electroosmotic nanofluid transport driven by peristalsis is considered, taking into account magnetohydrodynamics, viscous dissipation, and thermal radiation. The resulting equations are simplified using the lubrication approach and exact solutions for various parameters are obtained. The impact of different physical parameters on nanofluid flow is analyzed graphically. The study reveals that stronger electric fields accelerate entropy generation, higher temperatures are observed for blade nanoparticles, stronger magnetic fields reduce the size of the bolus, and blood-platinum-based nanofluid has higher velocities compared to blood-copper-based nanofluid.
