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 fullNewton iteration scheme. Results have been obtained for various values of the inner to the outer ...

Compression molding of semiconcentrated fiber suspensions: Flow and fiber orientation
(Publ by ASME, 1993)The focus of this paper is compression molding of semiconcentrated fiber suspensions. During compression molding a premeasured amount of raw material (charge) is placed between two halves of a die. The die is then closed ...

Effects of periodic gravity modulation in microgravity convection systems
(Publ by ASME, 1993)Natural convection in an enclosure that is subjected to periodic excitations is investigated using a classical mixed Galerkin finite element method. The modulation is incorporated in the momentum equations, through a ...

Article
Effects of the consistency of the fringing magnetic field on direct numerical simulations of liquidmetal flow
(2011)We investigate the effects of the consistency of strong fringing decreasing magnetic fields on numerical simulations of classical experimental data. Studies about fringing magnetic fields have attracted the attention of ...

Article
Injection molding using a generalized eulerian lagrangian formulation
(1993)A mathematical and a numerical approach to model the injection mold filling stage is presented. The approach is based on a Generalized Eulerian Lagrangian (GEL) formulation. In purely Lagrangian formulations the solution ...

Article
Numerical simulations of constantinflux gravity currents in confined spaces: Application to thermal storage tanks
(2016)This study uses Computational Fluid Dynamics (CFD) to investigate numerically the flow phenomena in the intrusion region of a thermal storage water tank during discharge. The early times of the discharging process have ...

Article
On the classification of similarity solutions of a twodimensional diffusionadvection equation
(2007)We consider the twodimensional diffusionadvection equation ut = Duyy  frac(d k, d u) ux. We present the classification of Lie symmetries of this equation. For the case k(u) = u2 we give the complete list of similarity ...

Article
Particle deposition in a realistic geometry of the human conducting airways: Effects of inlet velocity profile, inhalation flowrate and electrostatic charge
(2016)Understanding the multitude of factors that control pulmonary deposition is important in assessing the therapeutic or toxic effects of inhaled particles. The use of increasingly sophisticated in silico models has improved ...

Article
Transient planar squeeze flow of semiconcentrated fiber suspensions using the DinhArmstrong model
(2007)Numerical simulations are undertaken for the transient squeeze flow between parallel plates under a constant load. The conservation equations are solved via the finite element method in space and the CrankNicolson method ...

Article
A twodimensional numerical study of the stickslip extrusion instability
(2007)The timedependent, compressible extrusion of a Carreau fluid is solved over the reservoirdieextrudate region using finite elements in space and a fully implicit scheme in time. A nonmonotonic slip law based on experimental ...
