Impact of radially non-symmetric multiple stenoses on blood flow through an artery

The impact of radially non-symmetric multiple stenosis on blood flow through an artery have been analyzed by assuming blood as Power-law fluid model. The equations governing the flow of the proposed model are solved and closed from expressions for the blood flow characteristics, namely, dimensionless resistance to flow and wall shear stress at maximum depression for different points of a single loop stenosis. It has been found that the resistance to flow and wall shear stress decreases as stenosis shape parameter increases while both increases as stenosis size and stenosis length increases. This model is able to predict the main characteristics of the physiological flows and may have some interest in biomedical application.
