Description	Úloha laminárního vazkého proudění nestlačitelné newtonské kapaliny idealizovaným 2-D modelem bypassu je numericky řešena pomocí MacCormackova a Runge-Kuttova schématu. Obě schémata jsou formulována ve smyslu metody konečných objemů na strukturované čtyřúhelníkové síti. Model bypassu s pevnými stěnami zahrnuje proximální a distální části zúžené artérie včetně „end-to-side“ bypassového štěpu. V příspěvku jsou řešeny tři případy 75% stenózy s různým umístěním: oboustranná symetrická stenóza a dvě jednostranné stenózy, přičemž tvar zúžení je popsán pomocí Gaussovy funkce. Je provedena analýza a porovnání výsledn (cs) The problem of laminar viscous flow of an incompressible Newtonian fluid through an idealized 2-D bypass model with a stenosed host tube is solved using the finite volume approach of the MacCormack and Runge-Kutta schemes. The bypass model with rigid walls includes the proximal and distal parts of the stenotic host tube together with the end-to-side bypass graft. Three cases with a different position of the 75% stenosis are considered: the symmetric and two asymmetric, whereas the shape of the stenosis is described by the Gaussian function. The resulting velocity, pressure distribution and wall shear stress obtained from both computational schemes in all three cases are analyzed and compared with each other.
