Computational simulations demonstrated that wall shear stress and pressure drop in stenosed arteries increase with decreasing artery size, non-Newtonian fluid assumptions, and stronger magnetic fields.
Computational modeling demonstrates that non-Newtonian fluid dynamics and magnetic fields significantly increase wall shear stress and pressure drop in stenosed arteries.

May heighten stresses in small stenosed vessels under magnetic fields; leaves open in vivo validation before clinical relevance.
Steady flow simulations of blood flow in an axisymmetric stenosed artery, subjected to a static magnetic field, are performed to investigate the influence of artery size, magnetic field strength, and non-Newtonian behavior on artery wall shear stress and pressure drop in the stenosed section. It is found that wall shear stress and pressure drop increase by decreasing artery size, assuming non-Newtonian fluid, and increasing magnetic field strength. In the computations, the shear thinning behavior of blood is accounted for by the Carreau-Yasuda model. Computational results are compared and found to be inline with available experimental data.

Alshare et al. (2013) studied Stenosed arteries. Static magnetic field and non-Newtonian fluid assumptions was evaluated on Wall shear stress and pressure drop. Computational simulations demonstrated that wall shear stress and pressure drop in stenosed arteries increase with decreasing artery size, non-Newtonian fluid assumptions, and stronger magnetic fields.
