| Abstract: | Pulsatile flow patterns of three typical models for simulating large vessel,arterial stenosis and artificial heart valve were visualized and analysed by means of the experimental technique of dynamic now birefringence.velocity profiles,shear stress as well as the phase relation between the flow rate and the pressure were discussed.Especially,the now rate waveform obtained from the dynamic birefringence analysis is in good agreement with the measured data.This indicates that the dynamic birefringence technique and simplified relation presented in this paper can be used to obtain the high quality simulation of the pulsatile flow. |
