Using the theoretical approach of Bersted and Slee, we developed a technique of determining the molecular weight distribution (MWD) from the viscosity vs. shear rate flow curve. Each molecular weight fraction was assumed to have a characteristic deformation rate. Below this rate, the viscosity was...

4) shear rate 切变速率 1. The calculation of melt shear rate, jet stretch ratio and spinneret back pressure was analyzed and discussed, which decided the diameter and L/D ratio of spinneret. 分析了涤纶长丝生产中喷丝板选用的相关理论 ,对熔体的切变速率、喷丝头拉伸比、喷丝板背压的计算方法...
For a Newtonian fluid the viscosity is simply the shearing stress divided by the shear rate; viscosity does not vary with shear rate. Dilute polymer solutions under conditions normally used in capillary viscometry measurements are very nearly Newtonian and incompressible. Kinematic viscosity is a ...
The developed model provides a realistic process representation and it is used to test and verify the multivariable controller, which has been designed to maintain viscosity curves of the non-Newtonian fluid within a given region of the viscosity-vs-shear rate plane in presence of process ...
The shear rate above is referred to as the apparent shear rate, as it is equal to the actual shear rate only in the case of a Newtonian fluid. These formulae, when used in conjunction with Equation (1) above, lead to an expression which relates the viscosity, η, to these same ...
Although they generally do not change the relationship between shear stress and shear rate, they significantly change the magnitude of viscosity, therefore they must be considered. Only at a very high pressure (larger than 0.2 GPa), will pressure significantly influence viscosity. Therefore pressure ...
Kinematic Viscosity: Newtonian vs. Non-Newtonian Fluids A Newtonian fluid is a fluid that maintains constant viscosity across all shear rates (shear stress varies linearly with shear rate). These fluids are called Newtonian because they follow the original formula established by Sir Isaac Newton in ...
