On Peristaltic Casson Nanofluid Between Two Coaxial Porous Cylinders

The Peristaltic nanofluid flow across two coaxial porous cylinders is modelled mathematically. The blood is chosen as the base fluid, whose viscoelastic characteristics are carried through the Casson model. Furthermore, the zinc oxide nanoparticles are suspended in blood to form a nanofluid. The regular perturbation technique, utilizing small parameters, is employed to analyze the resulting system of equations. This method relies on a small wave number and the Casson parameter. The moderate Reynolds assumption is adopted for finding the solutions for temperature, pressure, electric potential, and both radial and axial velocities. Several physical parameters, including the Casson parameters, inner tube velocity, electromagnetic interaction parameter, Reynolds number, and porosity are examined in graphical format. The outcomes show that radial velocity diminishes for radius ratio and porosity parameter. However, it increases with the Casson parameter and wave number. Furthermore, the axial velocity also rises with wave number and Reynolds number. Temperature falls with both the radius ratio and amplitude ratio, while it rises with the porosity parameter. The electric potential function elevates with Casson fluid parameter and decreases with the radiation parameter. Casson fluid and porosity parameter elevates the pressure, while it decreases with Reynolds number. This study makes potential contributions to biomedical and environmental applications.
