Pulsatile flow occurs in medical devices, impacting heat transfer and fluid behavior. It has practical significance
in several disciplines, including thermodynamic devices. Pulses in flow and pressure influence pipe systems,
reciprocating pumps, and compressors. Motivated by this, we simulated corrugated microchannel with Jeffery
fluid flow enhanced by tri-nanoparticles to investigate this type of flow in detail. The model assumed that, in
addition to external temperature influences, conduit walls experience electric and magnetic fields, governed by
momentum and heat equations, along with electric potential and pulsing pressure equations. Using the perturbation
method and Mathematica software, we derived semi-analytical solutions for the governing partial differential
equations in their complex form. nanoparticle-enhanced blood exhibits improved thermal performance
compared to pure fluid, with the type and concentration of nanoparticles (Fe3O4, Au, SWCNTs) significantly
impacting heat dissipation and temperature distribution within the microfluidic conduit. Higher nanoparticle
concentrations increase liquid viscosity, reducing velocity inside the conduit; however, a magnetic field can
reverse this effect. This study underscores the application of pulsatile flow in heart pumps, where optimizing
thermal characteristics can enhance device efficiency and patient outcomes |
