【摘要】 目前普遍使用的毛细管式血液粘度计一般只能给出两个切变率下的粘度值,而且高切和低切所对应的切变率的具体值又不确切。为此,本文提出了一种解决毛细管粘度计测量非牛顿流体(如血液)的粘度时切变率不可知的问题的方法,提出了一种结构设计模型,并推导出了切变率—粘度—体积流量的关系,并以测量不同切变率下的粘度为例给出了仪器结构设计模型。更多还原

【Abstract】 A new method of measuring non-Newtonian fluids(such as blood) with capillary viscometer which can overcome the shear rate incertainty was developed. A structure model of the capillary viscometer was given. The relation among the shear rates, viscosities and volume flow of non-Newtonian fluids was accepted.更多还原
