The effect of stenotic geometry and non-Newtonian property of blood flow through arterial stenosis.

The effect of stenotic geometry and non-Newtonian property of blood flow through arterial stenosis. Cardiovasc Hematol Disord Drug Targets. 2019 May 09;: Authors: Sriyab S Abstract A mathematical model of non-Newtonian blood flow through different stenosis, namely bell shape and cosine shape, are considered. The non-Newtonian model is characterized by Power-law model. We obtain physiologically important flow quantities of blood flow behavior such as resistance to flow, skin friction and blood flow rate. We find that the cosine geometry exhibits higher resistance to flow, flow rate, and lower skin friction than the bell geometry. We not only study the effect of stenotic geometry but also study the effect of stenosis depth and stenosis height on the flow quantities. Moreover, we adjust the power law index to explore the non-Newtonian behavior. When blood exhibits Newtonian behavior, the resistance to flow and skin friction decrease but the blood flow rate increases. PMID: 31072297 [PubMed - as supplied by publisher]
