TL;DR: In this article, the effects of rheology, the science of deformation and flow behavior with gel-inoil-in-gel type low amplitude oscillatory shear measurements are described.
Abstract: Official Full-Text Publication: Rheological characterization of gel-in-oil-in-gel type low amplitude oscillatory shear rheology and creep recovery measurements. with the effects of rheology, the science of deformation and flow behavior. Rheology Handbook: For Users of Rotational and Oscillatory Rheometers PDF. Rotational (oscillatory) rheometers (referred to in road engineering as Dynamic Rheometers – DSR) are complex devices designed to characterize rheological.
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.
Abstract: New experimental data obtained from constant stress rheometers are used to show that the yield stress concept is an idealization, and that, given accurate measurements, no yield stress exists. 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.
TL;DR: In this paper, the authors compared powder flowability measurements using the two methodologies available from a Freeman FT4 powder Rheometer, including the twisted blade method and automated shear cell.
