      Numerical simulation of the extrusion of strongly compressible Newtonian liquids 

      Taliadorou, Eleni G.; Georgiou, Georgios C.; Mitsoulis, Evan C. (2008)
      The axisymmetric and plane extrusion flows of a liquid foam are simulated assuming that the foam is a homogeneous compressible Newtonian fluid that slips along the walls. Compressibility effects are investigated using both ...

      Perturbation solutions of Poiseuille flows of weakly compressible Newtonian liquids 

      Taliadorou, Eleni G.; Neophytou, Marios; Georgiou, Georgios C. (2009)
      Both the planar and axisymmetric isothermal Poiseuille flows of weakly compressible Newtonian liquids with constant shear and bulk viscosities are solved up to the second-order. A linear equation of state is assumed and a ...

      A two-dimensional numerical study of the stick-slip extrusion instability 

      Taliadorou, Eleni G.; Georgiou, Georgios C.; Alexandrou, Andreas N. (2007)
      The time-dependent, compressible extrusion of a Carreau fluid is solved over the reservoir-die-extrudate region using finite elements in space and a fully implicit scheme in time. A nonmonotonic slip law based on experimental ...

      Weakly compressible Poiseuille flows of a Herschel-Bulkley fluid 

      Taliadorou, Eleni G.; Georgiou, Georgios C.; Moulitsas, I. (2009)
      In this work, we derive approximate semi-analytical solutions of the steady, creeping, weakly compressible plane and axisymmetric Poiseuille flows of a Herschel-Bulkley fluid. Since the flow is weakly compressible, the ...
