The morphology of cell spheroids in simple shear flow

Frontiers in Physics
Cell spheroids are a widely used model to investigate cell-cell and cell-matrix interactions in a 3D microenvironment in vitro. Most research on cell spheroids has been focused on their response to various stimuli under static conditions.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Viscoelastic flow instability in planar shear flow

We report direct numerical simulations of elastic turbulence in shear-driven flow of a dilute polymer solution within a three-dimensional straight channel. Most existing approaches in the literature employ the Oldroyd-B model or its advanced version, the

Evolution of the wall shear stresses during the progressive enlargement of symmetric abdominal aortic aneurysms.

, 2006
The changes in the evolution of the spatial and temporal distribution of the wall shear stresses (WSS) and gradients of wall shear stresses (GWSS) at different stages of the enlargement of an abdominal aortic aneurysm (AAA) are important in understanding

The role of shear flow collapse and enhanced turbulence spreading in edge cooling approaching the density limit

Nuclear Fusion
Experimental studies of the dynamics of shear flow and turbulence spreading at the edge of tokamak plasmas are reported. Scans of line-averaged density and plasma current are carried out while approaching the Greenwald density limit on the J-TEXT tokamak.

Shear viscosity and nonlinear behaviour of whole blood under large amplitude oscillatory shear [PDF]

, 2013
We investigated experimentally the rheological behavior of whole human blood subjected to large amplitude oscillatory shear under strain control to assess its nonlinear viscoelastic response.

Electrorheological characterization of complex fluids used in electrohydrodynamic processes: Technical issues and challenges

Applied Rheology
The electrorheological (ER) characterization of low-viscosity fluids is paramount for producing micro- and nanoscale products through electrohydrodynamic (EHD) techniques, such as EHD-jet printing, electrospray, and electrospinning.

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading

Advanced Engineering Materials, EarlyView.
The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Evaluation of bed shear stress under turbid flows through measures of flow deceleration

, 2006
In previous work it has been observed that the direct application of the law-of-the-wall in flows of high concentrations of cohesive sediments, results in overestimation of the bed shear stress.
