Journal ArticleDOI

The yield stress myth

TL;DR: In this article, the simple Cross model is shown to be a useful empiricism for many non-Newtonian fluids, including those which have hitherto been thought to possess a yield stress.
Journal ArticleDOI

Flow characteristics associated with abrupt changes in geometry in the case of highly elastic liquids

TL;DR: In this article, the influence of small changes in corner geometry on flow characteristics in the case of elastic liquids flowing in various contraction geometries was considered and it was shown that it is very difficult to make generalizations from one geometry to another or from one type of non-Newtonian fluid to another.
Journal ArticleDOI

On the extensional viscosity of mobile polymer solutions

TL;DR: In this article, the authors describe experimental results on the extensional viscosity of mobile polymer solutions obtained from two instruments, the first being a commercial Spin Line Rheometer and the second a custom-built lubricated-die Converging Flow Rheometers.
Journal ArticleDOI

On the use of flow through a contraction in estimating the extensional viscosity of mobile polymer solutions

TL;DR: In this paper, the authors used pressure measurements in contraction flows in determination of the extensional viscosity behavior of polymer solutions, and concluded that contraction flows provide a convenient means of determining the extension viscosities of shear-thinning polymer solutions.
