Peristaltic pumping of hybrid nanofluid between concentric tubes with magnetic device effects: Applications to human endoscopy

The applications of hybrid nanomaterials report excellent thermal performances and convey applications in various processes like energy production, extrusion processes, nuclear reaction, manufacturing and engineering processes, industrial domains, aero-spaces etc. Additionally, the impacts of magnetic devices in advance endoscopy and biological transport phenomena are also a hot topic of research in the current era. This study deals with the physical influences of magnetic device on the peristaltic transport of a viscoplastic nanofluid between the two-dimensional curved concentric tubes. The curved shape structure of flow geometry from the external side with a flexible complex nature of the peristaltic endoscope present inside that is similar to the endoscopy of a living organ. The non-Newtonian Casson liquid polymer is employed for assist the dynamic of viscoplastic materials. The concentration of silver (Ag) and alumina (Al2O3) nanoparticles are utilized in the clay as a base fluid. The governing equations are modeled by using the curvilinear coordinates. The conducting investigation is worked out for creeping pattern and under the high wavelength consideration. The analytical proceedings for flow features, for examples, axial velocity profile, pressure gradient, pressure rise, shearing stress tensor and temperature profile, are obtained by using integration technique. It is noted that the velocity magnitude for viscous fluid is larger in magnitude as compared with the viscoplastic fluid. The magnitude of temperature rate get slower variation for volumetric concentration parameter (range of concentration parameter is 0%–4%). The current model has been used in bio-engineering processes, industrial fluid mechanics, thermal processing, endoscopy of living organs and cooling systems.
