Simulation for bloodstream conveying bi-nanoparticles in an endoscopic canal with blood clot under intense electromagnetic force

Abstract

In the current era, the electromagnetic pumping flow of hybrid nano-biofluid features in myriad magneto-biomedical engineering applications. In this scenario, the current disquisition is centralized to unfold the electro-magneto-hemodynamic distinctive features of ionized bloodstream conveying silver and aluminium oxide hybridized nanoparticles driven by electroosmosis via an endoscopic conduit (space between two coaxial tubes) formed by a uniform and rigid endoscope and a complaint walled artery. The formulation involves the dominance of Hall and ion-slip factors, internal energy generation, Joule warming, a blood clot (coagulation), and convective wall condition. The contribution of nanoparticles' shape is dissected in this examination. The Poisson-Boltzmann equation is utilized to emulate the conduit's electric double layer (EDL). The lubrication and Debye-Hückel linearization principles are opted to simplify the normalized complicated leading equations. The homotopic series solutions of the consequent coupled nonlinear dimensionless equations are computed. A critical examination of significant flow-controlling parameters over the relevant hemodynamical characteristics is executed via graphs and tables. From the obtained outcomes, it is worthy of imparting that a discernible lesson is viewed in the blood velocity profile against the intensified estimates of Hall and ion-slip, and electro-osmotic factors. Blood is warmed with a positive Joule heating factor, whereas it is cooled with negative values of this factor. Upraised volumetric proportions of hybridized nanoparticles cool the blood in the conduit. Streamline patterns are also graphically displayed to see the blood flow pattern and the formation of entrapped boluses in the endoscopic domain. This research study considering multiple physical aspects such as electromagnetic phenomena, electromagnetic force, inclusion of hybridized nanoparticles, and coagulation is an innovative approach. Our findings in this simulation are expected to open up a new opportunity in biomedical engineering applications, including magneto-endoscopic operation, cheap devices for drug distribution, bio-magnetic therapy, electromagnetic hyperthermia treatment for cancer, etc.
