Numerical investigation of Casson fluid flow performance of blood containing gold and Fe₃O₄ nanofluid injected into a stenotic artery

Abstract

The study of the movement of blood across a stenotic artery is an important one in the discipline of mathematical fluid mechanics because of the importance it has in the field of biomedical research. The current study’s primary objective is to learn how nanoparticles influence blood flow through a narrowed artery. Within an examination of the theoretical flow situation, we investigate the importance of Casson nanofluid flow across a heart artery. Similarity transformations aid in the conversion of the partial differential equations into ordinary differential equations. After that, the non-dimensional equations are solved by using the MATLAB software in the Bvp5c technique. Enhancing the magnetic characteristics of the blood stream tissues was explored by boosting the magnetic field parameter, leading to a decrease in blood circulation as expected. At higher values of the Casson fluid parameter, the velocity profile decreased. Increasing the concentration of gold particles in the narrowed artery makes it more efficient at transferring heat. The use of iron nanoparticles in medicine delivery is supported by an argument. The method that is currently being used may be of assistance in dispersing pharmaceuticals across the blood stream. We employ a visual representation to facilitate the presentation of this drug delivery mechanism’s theoretical outcomes.
