This model is based on a long wave approximation of the Navier-Stokes equations and requires no a priori estimation, contrary to classical 1D models. The wall shear stress (WSS), the axial velocity profiles and the flow rate computed with the multiring model are in good agreement with the linear Womersley solution whereas classical 1D models’ solutions are much less accurate. 000013823 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000013823 653__ $$a 000013823 7112_ $$a24th International Congress of Theoretical and Applied Mechanics$$cMontreal (CA)$$d2016-08-21 / 2016-08-26$$gICTAM2016 000013823 720__ $$aGhigo, Arthur, R. 000013823 8560_ $$ffischerc@itam.cas.cz 000013823 8564_ $$s137952$$uhttps://invenio.itam.cas.cz/record/13823/files/PO.FM01-1.02.55.pdf$$yOriginal version of the author's contribution as presented on CD, XMLout( page 456, code PO.FM01-1.02.55). 000013823 962__ $$r13812 000013823 980__ $$aPAPER
