Effects of Pulsatile Inlet Conditions on the Hemodynamic Conditions of Stent with Deformed Wall Simulations

Human blood flow is naturally working as a pulsatile flow under the influence of heartbeat cycle. As many blood flow simulation studies have been conducted recently, many assumption and simplification of intravascular flow phenomena were used as the boundary condition of the simulation. For example, stent contact rigid wall condition, steady blood flow also material simple models and properties of tissues and blood. However, these simplifications may lead to inaccuracy of the results and analysis. This paper tries to observe the simulation results from different boundary conditions which include the pulsatile flow conditions and how it behaves compared to the steady flow. From the investigation and comparison, the difference between results of flow parameters obtained from the pulsatile and steady simulation shows 2.2% deviation on the appearance of low WSS along the deployment area.
