Flow onset for a single bubble in yield-stress fluids [PDF]
We use computational methods to determine the minimal yield-stress required in order to hold static a buoyant bubble in a yield-stress liquid. The static limit is governed by the bubble shape, the dimensionless surface tension ($\gamma$) and the ratio of the yield-stress to the buoyancy stress ($Y$).

Change of the yield stress in roll formed ERW pipes considering the Bauschinger effect [PDF]
ERW pipes formed with the roll forming process show a yield stress distribution along the circumferential direction and their quality is strongly influenced by the magnitude and by the distributions of the yield stress.

Hydrogel Formulation for Sealing Cracked Wellbores for Co2 Storage
A challenge for underground CO2 storage is the leakage of the buoyant supercritical gas through microcracks in wellbores that cannot be sealed with current oilfield cements that are too viscous and cannot penetrate the cracks.

Rheology as a Tool for Fine-Tuning the Properties of Printable Bioinspired Gels
Over the last decade, efforts have been oriented toward the development of suitable gels for 3D printing, with controlled morphology and shear-thinning behavior in well-defined conditions.

Analysis of the flowability of cohesive powders using Distinct Element Method [PDF]
Computer simulations using Distinct Element Method (DEM) have been carried out to investigate the effect of cohesion on the flowability of polydisperse particulate systems. For this purpose, two assemblies with different values of surface energy and made

Rheological Behavior of Cement Paste: A Phenomenological State of the Art
With the interest aroused by the development of modern concretes such as printable or self-compacting concretes, a better understanding of the rheological behavior, directly linked to fresh state properties, seems essential.

Cavitation Rheology of Model Yield Stress Fluids Based on Carbopol [PDF]
Measuring surface tension of yield stress fluids has remained a critical challenge due to limitations of the traditional tensiometry techniques. Here, we overcome those limits and successfully measure the surface tension and mechanical properties of a model yield stress fluid based on Carbopol gels via a needle-induced cavitation (NIC) technique.

Analysis of dynamics variation against thixotropic parameter’s preferential range [PDF]
Variation in the dynamics of a steady-state blood flow through a stenosed tapered artery has been investigated corresponding to changes in thixotropic parameter λ over the range [0,1].
