Abstract:
PURPOSE: Characteristics of pulsatile flow in 3-dimensional arterial geometry and elastic vessel wall should be investigated in order to understand the physiological blood flow in human body. In this study, the modelling of the physiological blood flow in the elastic blood vessel is proposed. METHODS: The finite volume predictions are used to analyse the pulsatile flow characteristics in the elastic blood vessel. RESULTS AND CONCLUSION: Variations of the pressure and the velocity waveforms are obtained using the proposed modelling. The magnitudes of the pressure waveforms in the elastic blood vessel model are bigger than those of the rigid blood vessel model.
