The commercially available computational fluid dynamics code (CFD), FLUENT, has been used for these studies. Two different experiments were modeled involving pulsatile flow through axisymmetric stenoses. Four different turbulence models were employed to study their influence on the results. It was found that the low Reynolds number k-\u03c9 turbulence model was in much better agreement with previous experimental measurements than both the low and high Reynolds number versions of the RNG (renormalization-group theory) k-\u03b5 turbulence model and the standard k-\u03b5 model, with regard to predicting the mean flow distal to the stenosis including aspects of the vortex shedding process and the turbulent flow field. All models predicted a wall shear stress peak at the throat of the stenosis with minimum values observed distal to the stenosis where flow separation occurred.<\/jats:p>","DOI":"10.1115\/1.1589774","type":"journal-article","created":{"date-parts":[[2003,8,8]],"date-time":"2003-08-08T10:45:07Z","timestamp":1060339507000},"page":"445-460","update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":166,"title":["Numerical Modeling of Pulsatile Turbulent Flow in Stenotic Vessels"],"prefix":"10.1115","volume":"125","author":[{"given":"Sonu S.","family":"Varghese","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, Purdue University, West Lafayette, IN 47907"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Steven H.","family":"Frankel","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Purdue University, West Lafayette, IN 47907"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2003,8,1]]},"reference":[{"key":"2019100423023821100_r1","doi-asserted-by":"crossref","unstructured":"Ku, David N. , 1997, \u201cBlood Flow in Arteries,\u201d Annu.
