A numerical investigation of blood flow in an arterial segment with periodic body acceleration

Abstract

A fluid convection flow driven by a periodic body acceleration with thermal stratification in an arterial cross section filled with an incompressible Newtonian fluid (blood) is studied. A two-dimensional computational visualization technique is used to study the steady flow behavior of the viscous electrically conducting fluid flow. The driving force is generated by putting an external magnetic field in the transverse direction of the flow. A numerical method based on the pressure correction iterative algorithm (SIMPLE) is adopted to compute the flow field and temperature along the arterial cross section. Variation over a wide range of parameters such as Prandtl number, Hartmann number, and Womersley number have been investigated for the flow and heat transfer characteristics.
