      Annular liquid jets at high Reynolds numbers 

      Georgiou, Georgios C. (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 ...

      Converged solutions of the Newtonian extrudate-swell problem 

      Georgiou, Georgios C.; Boudouvis, Andreas G. (1999)
      Both the axisymmetric and the planar Newtonian extrudate-swell problems are solved using the standard and the singular finite element methods. In the latter method, special elements that incorporate the radial form of the ...

      The steady annular extrusion of a Newtonian liquid under gravity and surface tension 

      Housiadas, Kostas D.; Georgiou, Georgios C.; Tsamopoulos, J. (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 ...

      Steady flow of a two-dimensional film under pressure 

      Georgiou, Georgios C.; Tsamopoulos, J.; Schultz, W. W. (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 ...

      A study of various factors affecting Newtonian extrudate swell 

      Mitsoulis, Evan C.; Georgiou, Georgios C.; Kountouriotis, Zacharias (2012)
      Finite-element simulations have been undertaken for the benchmark problem of extrudate swell present in extrusion. Both cases of planar and axisymmetric domains were considered under laminar, isothermal, steady-state ...

      Thin films: Increasing the complexity of the model 

      Sophocleous, Christodoulos; Leach, Peter G. L. (2012)
      Thin films arise in a variety of contexts. They can be between two solid surfaces in the form of a lubricant or with one surface solid and the other free as in water or oil on a road. When the surface tension is a dominant ...
