Hemodynamics analysis for cosine shaped stenoses to blood flow behavior

The Study of flow over stenoses have been investigated by many researchers. In these cases, the more realistic the models are, the higher the acceptability of the results. For this study, a very common shape of stenosis, that is modified cosine, are modeled. Newtonian and non-Newtonian blood flow al...

description The Study of flow over stenoses have been investigated by many researchers. In these cases, the more realistic the models are, the higher the acceptability of the results. For this study, a very common shape of stenosis, that is modified cosine, are modeled. Newtonian and non-Newtonian blood flow along with the pulsatile flow conditions was used. The results show that tendency for recirculation to occur reduces as the stenosis expands in the longitudinal direction. On the other hand, higher tendency for recirculation of blood is observed if the stenosis expands in the transverse direction. The wall shear stress is observed to decrease as the stenosis expands in the longitudinal direction but no significant changes is observed if the stenosis expands in the other direction. Similar patterns of flow are observed for both Newtonian & non-Newtonian flow condition but the non-Newtonian flow tends to produce higher WSS.
