... solver is not required to model these behaviors. The turbulent solutions obtained in the current work predict WSS values along the stenoses that are on average 35% higher than those calculated for laminar flow conditions. There is also a small but unsystematic shift in the spatial positions at which...

A direct numerical simulation is carried out for the laminar flow case while the turbulent flow is investigated with two different unsteady statistical turbulence modeling...
