Also, compared with experimental data, the results show that, up to 70% stenosis, the flow is laminar and for 80% stenosis the flow becomes turbulent. Assuming laminar or turbulent flow and also rigid or elastic walls, the results are compared with each other. The investigation of time-averaged shear stress and the oscillatory shear index for 80% stenosis show that assuming laminar flow will cause more error than assuming a rigid wall. The results also show that, in turbulent flow compared with laminar flow, the importance of assuming a flexible artery wall is more than assuming a rigid artery wall.<\/jats:p>","DOI":"10.1155\/2015\/515613","type":"journal-article","created":{"date-parts":[[2015,8,31]],"date-time":"2015-08-31T21:49:48Z","timestamp":1441057788000},"page":"1-10","source":"Crossref","is-referenced-by-count":40,"title":["Numerical Study of Turbulent Pulsatile Blood Flow through Stenosed Artery Using Fluid-Solid Interaction"],"prefix":"10.1155","volume":"2015","author":[{"given":"Mehdi","family":"Jahangiri","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering, Isfahan University of Technology, Isfahan 8415683111, Iran"}]},{"given":"Mohsen","family":"Saghafian","sequence":"additional","affiliation":[{"name":"Department of Mechanical Engineering, Isfahan University of Technology, Isfahan 8415683111, Iran"}]},{"given":"Mahmood Reza","family":"Sadeghi","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, University of Isfahan, Isfahan 8174673441, Iran"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1749-6632.1997.tb52003.x"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2003.11.026"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2003.08.014"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1115\/1.1403025"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1115\/1.2798332"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/s0045-7949(99)00019-x"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1115\/1.1385840"},{"key":"11","first-page":"111","volume":"2","year":"1972","journal-title":"Cardiovascular Fluid Dynamics"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(76)90169-x"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1017\/s0022112080002431"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(83)90065-9"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(84)90123-4"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/s0006-355x(99)80011-0"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1115\/1.2401182"},{"key":"18","year":"2011"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1115\/1.1589774"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1115\/1.2937744"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1016\/j.jbiomech.2011.08.017"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardiores.2003.11.036"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.98.2.157"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1161\/01.cir.98.19.2000"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1161\/01.atv.17.5.912"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1161\/01.atv.5.3.293"},{"key":"28","doi-asserted-by":"publisher","DOI":"10.1002\/jcp.21024"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.01082.2007"},{"key":"30","doi-asserted-by":"publisher","DOI":"10.1097\/00002480-199440020-00012"},{"key":"31","doi-asserted-by":"publisher","DOI":"10.1161\/01.res.22.2.165"},{"key":"32","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(79)90150-7"}],"container-title":["Computational and Mathematical Methods in Medicine"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2015\/515613.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2015\/515613.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cmmm\/2015\/515613.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,7,27]],"date-time":"2016-07-27T20:26:15Z","timestamp":1469651175000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cmmm\/2015\/515613\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":28,"alternative-id":["515613","515613"],"URL":"https:\/\/doi.org\/10.1155\/2015\/515613","relation":{},"ISSN":["1748-670X","1748-6718"],"issn-type":[{"value":"1748-670X","type":"print"},{"value":"1748-6718","type":"electronic"}],"subject":[],"published":{"date-parts":[[2015]]}}}
