Therefore almost all studies in the literature of viscoplastic flows are focused on laminar flow. However it is possible that the flow could be turbulent. In this work we performed DNS simulations in order to understand the flow when it undergoes a transition from laminar turbulent flow. Results will be shown for the general flow, the structure of the yielded and unyielded regions are well as the global flow characteristics such as the drag coefficient. 000016018 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000016018 653__ $$a 000016018 7112_ $$aCOMPDYN 2013 - 4th International Thematic Conference$$cIsland of Kos (GR)$$d2013-06-12 / 2013-06-14$$gCOMPDYN2013 000016018 720__ $$aAlexandrou, A.$$iKassinos, S.$$iXenis, F. 000016018 8560_ $$ffischerc@itam.cas.cz 000016018 8564_ $$s28117$$uhttps://invenio.itam.cas.cz/record/16018/files/2122.pdf$$yOriginal version of the author's contribution as presented on CD, section: SC-MS 08 COMPUTATIONAL NON-NEWTONIAN FLUID MECHANICS . 000016018 962__ $$r15525 000016018 980__ $$aPAPER
