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...
