Size and shape evolution of pores in a viscoplastic matrix under compression

The frequent use of soils and earth materials for hydraulic capping and for geo-environmental waste containment motivated our interest in detailed modelling of changes in size and shape of macro-pores to establish links between soil mechanical behaviour an ...

Bostwick degree and rheological properties: An up-to-date viewpoint

Paolo Perona

The correlation between the Bostwick degree and the static rheological properties of yield stress food fuids is first revisited and then reformulated in this work. The role of the yield stress in the free surface flow of the Bostwick test is studied using ...

Approximation of a nonlinear elliptic problem arising in a non-Newtonian fluid flow model in glaciology

Jacques Rappaz

The main goal of this article is to establish a priori and a posteriori error estimates for the numerical approximation of some non linear elliptic problems arising in glaciology. The stationary motion of a glacier is given by a non-Newtonian fluid flow mo ...

Squeeze flow of concentrated long fibre suspensions: experiments and model

Experimental squeeze flow results show that the behaviour of concentrated short fibre suspensions and concentrated long fibre suspensions impregnated with polymer melts are qualitatively different. Short fibre suspensions have a low yield stress, have an o ...

Crack growth in lamellar titanium aluminide

William Curtin

In-situ compact tension tests on binary lamellar titanium aluminide (TiAl) possessing the colony "polycrystalline" microstructure illustrate a range of damage phenomena and toughening mechanisms including crack nucleation across colony boundaries, plastic ...

Visualization of ice slurries and ice slurry flows

Didier Albert Simon Vuarnoz

Visualization of ice particles in a rectangular cavity and ice slurry flows in a pipe are performed. The form and size of ice particles is investigated by optical microscopy, which permits a statistical evaluation of the geometrical shapes of the ice cryst ...

HEAT TRANSFER OF ICE SLURRIES IN PIPES

Didier Albert Simon Vuarnoz

Some basic ideas of the heat transfer of ice slurries are discussed. The equations des-cribing a flow of a Bingham fluid through a tube with a heat flux over the boundary are presented. The theory shows that familiar Relations known in the field of heat ex ...

Heat slug propagation in QUELL. Part I: Experimental setup and 1-fluid GANDALF analysis

The experimental setup for heat slug propagation at zero current and field in the QUench Experiment on Long Length (QUELL) is described and re-evaluated. Eight inductively heated and four resistively heated runs are considered and analyzed with the 1-fluid ...

Model for the alignment of actin filaments in endothelial cells subjected to fluid shear stress

Jean-Jacques Meister

Cultured vascular endothelial cells undergo significant morphological changes when subjected to sustained fluid shear stress. The cells elongate and align in the direction of applied flow. Accompanying this shape change is a reorganization at the intracell ...
