人造血管水渗透率的理论探讨

Theoretical Studies on the Water Permeability of Artificial Vascular

将平纹织物简化成平行孔洞模型,根据当量直径的定义,建立人造血管水渗透率与织物经纬密和纱线直径的理论关系,以及人造血管水渗透率与织物紧度的理论关系.经验证:在忽略水的黏性时,所建立的理论关系可以用于水渗透率的预测及人造血管参数的设计.

Plain weave fabric mode was simplified into a model with parallel holes. On the basis of equivalent diameter, the relationship between water permeability of artificial vascular and parameters of the fabric （warp density, weft density, and yarn diameter）was established. The other relationship between the water permeability and the fabric tightness was set. Experiments showed that if the viscosity of water was neglected, the water permeability could be forecasted and the parameters of artificial vascular could be designed according to two relationships.
