Numerical analysis of the hydrodynamic behaviour of immiscible metallic alloys in twin-screw rheomixing process [PDF]
A numerical analysis by a VOF method is presented for studying the hydrodynamic mechanisms of the rheomixing process by a twin-screw extruder (TSE). The simplified flow field is established based on a systematic analysis of flow features of immiscible ...

On the modelling of isothermal gas flows at the microscale [PDF]
This paper makes two new propositions regarding the modelling of rarefied (non-equilibrium) isothermal gas flows at the microscale. The first is a new test case for benchmarking high-order, or extended, hydrodynamic models for these flows.

Instability and transition to turbulence in a free shear layer affected by a parallel magnetic field [PDF]
Instability and transition to turbulence in a temporally evolving free shear layer of an electrically conducting fluid affected by an imposed parallel magnetic field is investigated numerically. The case of low magnetic Reynolds number is considered.

Global bifurcations to subcritical magnetorotational dynamo action in Keplerian shear flow [PDF]
Magnetorotational dynamo action in Keplerian shear flow is a three-dimensional, non-linear magnetohydrodynamic process whose study is relevant to the understanding of accretion processes and magnetic field generation in astrophysics.

Aggregation of silica nanoparticles in concentrated suspensions under turbulent, shear and extensional flows. [PDF]
The production of nanoparticles in concentrated suspensions requires strict control of the stability of the systems which are strongly influenced by the physico-chemical properties and the hydrodynamic conditions they are placed in. This study deals with

Reynolds stresses and mean fields generated by pure waves: applications to shear flows and convection in a rotating shell [PDF]
A general reformulation of the Reynolds stresses created by two-dimensional waves breaking a translational or a rotational invariance is described. This reformulation emphasizes the importance of a geometrical factor: the slope of the separatrices of the

A note on nonlinear stability of plane parallel shear flows
We present a generalized energy functional E for plane parallel shear flows which provides conditional nonlinear stability for Reynolds numbers Re below some value ReE depending on the shear profile.
