Flow instabilities of Herschel-Bulkley fluids
(2003)
We investigate numerically the interactions of two-dimensional jets of Bingham plastic and Herschel-Bulkley fluids with a vertical surface at a distance from the die exit. This problem simulates the early stages of filling ...
Squeeze flow of semi-solid slurriesAAA
(2013)
A standard method used to determine material properties of semi-solid slurries is the squeeze flow experiment in which a fixed amount of material is squeezed under constant force or velocity. The relation between the force ...
The integrated singular basis function method for the stick‐slip and the die‐swell problems
(1991)
We further develop a new singular finite element method, the integrated singular basis function method (ISBFM), for the solution of Newtonian flow problems with stress singularities. The ISBFM is based on the direct ...
The compressible Newtonian extrudate swell problem
(1995)
We solve the compressible Newtonian extrudate swell problem in order to investigate the effect of compressiblity on the shape of the extrudate. We employ a first‐order equation of state relating the density to the pressure ...
Steady flow of a two-dimensional film under pressure
(2000)
We use finite elements and the full Newton iteration method to solve the steady, two-dimensional flow of a Newtonian planar film, issuing from a slit under a pressure difference between the two free surfaces, in the presence ...
The steady annular extrusion of a Newtonian liquid under gravity and surface tension
(2000)
The steady extrusion of a Newtonian liquid through an annular die and its development outside and away from the die are studied under the influence of gravitational and surface tension forces. The finite element method ...
Flow development in compression of a finite amount of a Bingham plastic
(2007)
The flow and shape evolution during the compression of a finite amount of a Bingham plastic is investigated by means of numerical simulations. The problem relates to the popular compression test used for the rheological ...
Annular liquid jets at high Reynolds numbers
(2003)
The flow of annular liquid jets at high Reynolds numbers is analysed by means of the finite element method and the full-Newton iteration scheme. Results have been obtained for various values of the inner to the outer ...
Squeeze flow of thixotropic semisolid slurries
(2014)
An essential element for the integration of a semisolid process in the production of complex commercial components is the availability of accurate mathematical and computational tools that could describe both the rheological ...
Squeeze flow of semi-solid slurries
(2013)
A standard method used to determine material properties of semi-solid slurries is the squeeze flow experiment
