Abstract
The current work analyzes the effects of concentric ballooned catheterization and heat transfer on the hybrid nano blood flow through diseased arterial segment having both stenosis and aneurysm along its boundary. A fractional second-grade fluid model is considered which describes the non-Newtonian characteristics of the blood. Governing equations are linearized under mild stenosis and mild aneurysm assumptions. Precise articulations for various important flow characteristics such as heat transfer, hemodynamic velocity, wall shear stress, and resistance impedance are attained. Graphical portrayals for the impact of the significant parameters on the flow attributes have been devised. The streamlines of blood flow have been examined as well. The present finding is useful for drug conveyance system and biomedicines.
Highlights
The current work analyzes the effects of concentric ballooned catheterization and heat transfer on the hybrid nano blood flow through diseased arterial segment having both stenosis and aneurysm along its boundary
The constriction of an artery or heart valve disturbing the normal bloodstream is known as stenosis and the associated disease is known as arteriosclerosis
The arterial wall shear stress in the stenosis segment increases to its maximum before it drops significantly and bottoms at the end of the stenosis segment, whereas the opposite trend of arterial wall shear stress is detected in the aneurysmal segment as compared to the stenosis segment
Summary
The current work analyzes the effects of concentric ballooned catheterization and heat transfer on the hybrid nano blood flow through diseased arterial segment having both stenosis and aneurysm along its boundary. The study of blood circulation via catheterized stenotic aneurysmal arteries is gaining prominence, owing to the ever-increasing requirements of science and medicine. Shit and Majee[4] investigated numerically, the flow pattern in a diseased artery segment with abdominal aortic aneurysm by considering both unsteady magneto-hydrodynamic (MHD) bloodstream and heat transfer models. Reddy et al.[12] investigated the incompressible and homogenous coupled-stress blood flow via a catheterized diseased stenotic tapered artery. Misra et al.[14] investigated the flow pattern of non-Newtonian blood in a stenosed artery when a catheter was inserted. Hypothetical examinations on single nanofluid and hybrid nanofluid can be found in21–30
