Assessment of unsteady-state thermal expansion in saccular aneurysms with Newtonian blood circulation including silver nanoparticles

Abstract

The current study is based on an examination of the effect of Newtonian blood flow on the value of the wall shearing stress of an intracranial aneurysm using computational fluid dynamics. Blood is frequently thought to behave like a Newtonian fluid in cerebral arteries. It is fully described how a saccular aneurysm affects a model of blood-silver (Ag) nanofluid flow via an artery. Blood is regarded as a based fluid because of its rheology. The blood flow is Newtonian, laminar, incompressible, viscous, and unsteady, blood enters with a velocity of 0.08 ms−1 and the arterial wall should be flexible. The novelty of the research is to examine the impact of nanoparticles (Ag) on saccular aneurysm. To find the solution, a time-dependent direct solver was employed. To get the answer, the finite element discretization method (FDM) is applied. Coupled partial differential equations are used to mathematically describe the rheology of blood. In the current analysis, the solutions for velocity, temperature, and pressure distribution are found. Figures are used to illustrate and quickly discuss the effects of physical parameters on the characteristics of arterial blood flow for silver nanoparticles. These findings will be extremely beneficial in the treatment of arteries with aneurysms.
