Flow Analysis of Non-Newtonian Blood in a Magnetohydrodynamic Pump

The magnetohydrodynamic (MHD) pump has attracted a lot of attention in today´s technology especially for biotechnology and drug delivery applications. In a MHD pump, the magnetic field creates a dynamic electromotive force that moves the fluid forward. The knowledge of the details of the flow field is needed for design of a MHD pump. The purpose of this study is to numerically investigate the flow of the blood, as a non-Newtonian fluid, in a MHD. A power law model for blood viscosity is utilized. To solve the nonlinear governing momentum and Maxwell equations, a computational fluid dynamic (CFD) code based on finite difference is utilized. The simulation results show that the velocity increases by increasing the magnetic flux density (B) and current (I).
