WANG Guilian, SUN Yunna, YAO Jinyuan, et al. Influence of small diameter artificial vessel wall structure on liquid flow field[J]. 2019, (10): 4-7. DOI: 10.13873/j.1000-9787(2019)10-0004-04.
Effects of artificial vessel wall structure prepared by 3 D print and spinning on the liquid flow field is simulated.Based on the fluid simulation module of the commercial Comsol software
the influence of the structure size and fluid viscosity on the internal flow field of artificial vessel are analyzed.The results show that stagnation zones are formed in the flow field of artificial vessel prepared with 3 D print
and increase with the increase of the projection size
but did not vary with the liquid viscosity.Through simulating the stagnation zones with thrombus block
it is proved that projection array has the enhancement effect on the thrombus block formulation inside of the artificial vessel wall.
