Computational modelling and simulation of biomagnetic fluid flow in a stenotic and aneurysmal artery

This thesis is concerned with the development of mathematical models for the computation and simulation of biomagnetic fluid flow in either a stenosed or aneurysmal artery in the presence of non-uniform magnetic fields. The mathematical models take into account blood rheology where blood behaves as...

description	This thesis is concerned with the development of mathematical models for the computation and simulation of biomagnetic fluid flow in either a stenosed or aneurysmal artery in the presence of non-uniform magnetic fields. The mathematical models take into account blood rheology where blood behaves as a magnetic fluid due to the complex interaction of intercellular protein, cell membrane and haemoglobin. The present study involves steady three-dimensional biomagnetic fluid flow and mass transfer through a horizontal cylinder. Numerical solutions obtained through a finite volume method shows that the magnetisation force has an effect on the fluid concentration and exerts a greater influence on the secondary flow motions compared to that caused by the Lorentz force.
