This analysis reveals how a magnetic field affects flow and shear stress in micropolar nanofluids, indicating important implications for arterial health.
In this paper, the impact of a magnetic field on blood flow with nanofluid particles through an inclined porous stenosed artery and dilatation was studied. Here blood is treated as micropolar fluid. The equations are solved by using Homotopy perturbation method [HPM] under the assumption of mild stenosis. The closed form solutions of velocity, temperature profile, and concentration distribution are obtained. The effects of pertinent parameters on flow phenomena have been observed and results are analyzed graphically. This study examines the impact of the magnetic parameter on flow characteristics and reveals that the presence of a magnetic field increases resistance to the flow while decreasing shear stress at the wall. A result is found that the flow resistance and shear stress at the wall decreased for heights of the stenosis dilatation. Additionally, the study finds that resistance to the flow increases and shear stress at the wall decreases with viscosity. The stream lines are drawn to examine the flow pattern and properties of momentum transfer.
