Gotsis DA, Ke Q (1999) Comparison of three methods to measure the elongational viscosity of polymer melts: entry flow, fiber spinning and uniaxial elongation. Presented at SPE ANTEC 1999, New YorkGotsis D A,Ke Q.Comparison of three methods to measure the elongational viscosity of polymer melts...
This work looks into the repeatability, benefits and duration of two test methods to measure ZSV: the creep test and frequency sweep test. To account for the influence of the asphalt type, six different conventional and modified asphalts were tested. A statistical analysis was performed to ...
The quality control of colored paint generally adopts the rotary table type, which can measure the viscosity at several rotational speeds, and then draw the flow curve to measure the thixotropy.The determination method of the rotating disc rotary viscometer is specified in the American ASTM D2196-...
the model. Very interesting things happen. At a certain point, the u,max & cell number are related. I use this to estimate that numerical viscosity of the model. At the bottom end, it becomes a measure of the model 'stiffness' - at the top end, a measure of the solver viscosity. ...
Rheology is used to measure the shear storage and loss moduli of brain tissue in (1) healthy and tuberous sclerosis mouse brain and (2) healthy porcine brain. Next, cavitation rheology - a technique used to measure the elastic modulus of compliant polymers and tissues - is implemented for ...
Their processing requires the determination of rheological parameters such as viscosity, modulus, and yield stress value. We compare three methods to measure the yield stress of one particular soft solid system, i.e., concentrated surfactant systems, models for bar soap. One method is based on ...
Graphene energy transfer (GET) can be used to measure the distance between a graphene surface and a fluorescent dye. A new strategy for attaching DNA in a controlled orientation onto graphene now makes it possible to use GET to track the dynamics of DNA and protein–DNA interactions with base...
Our proofs work also under two alternative definitions of viscosity sub/supersolution which might be useful, in particular, in infinite dimensional spaces, for instance to study measure-valued processes. We prove the analogous result for stochastic processes that must satisfy boundary conditions, ...
There are six alternate methods or hydraulic systems that may be used to measure the hydraulic conductivity. These hydraulic systems are as follows: 1.1.1 Method A—Constant Head 1.1.2 Method B—Falling Head, constant tailwater elevation 1.1.3 Method C—Falling Head, rising tailwater elevation ...
Measurement of blood viscosity using a pressure‐scanning capillary viscometer. A newly designed pressure‐scanning capillary viscometer is extended to measure the viscosity of whole blood over a range of shear rates without the use of... Sehyun,Shin,Yunhee,... - 《Clinical Hemorheology & Microcir...
