      Cessation of annular Poiseuille flows of Bingham plastics 

      Chatzimina, Maria Evangelia; Xenophontos, Christos A.; Georgiou, Georgios C.; Argyropaidas, Ioannis; Mitsoulis, Evan C. (2007)
      We numerically solve the cessation of the annular Poiseuille flow of Bingham plastics for various values of the diameter ratio, using the regularized constitutive equation proposed by Papanastasiou and employing finite ...

      Cessation of Couette and Poiseuille flows of a Bingham plastic and finite stopping times 

      Chatzimina, Maria Evangelia; Georgiou, Georgios C.; Argyropaidas, Ioannis; Mitsoulis, Evan C.; Huilgol, R. R. (2005)
      We solve the one-dimensional cessation Couette and Poiseuille flows of a Bingham plastic using the regularized constitutive equation proposed by Papanastasiou and employing finite elements in space and a fully implicit ...

      Stability of the annular Poiseuille flow of a Newtonian liquid with slip along the walls 

      Chatzimina, Maria Evangelia; Georgiou, Georgios C.; Housiadas, Kostas D.; Hatzikiriakos, Savvas George (2008)
      The annular Poiseuille flow of a compressible Newtonian fluid is studied assuming that slip occurs along the wall. Different slip models relating the wall shear stress to the slip velocity are employed. In the case of ...

      Stability of the annular Poiseuille flow of a Newtonian liquid with slip along the walls 

      Chatzimina, Maria Evangelia; Georgiou, Georgios C.; Housiadas, Kostas D.; Hatzikiriakos, Savvas George (2009)
      The annular Poiseuille flow a Newtonian fluid is studied assuming that slip occurs along the walls. Different slip models relating the wall shear stress to the slip velocity are employed. In the case of non-monotonic slip ...

      Wall shear rates in circular couette flow of a Herschel-Bulkley fluid 

      Chatzimina, Maria Evangelia; Georgiou, Georgios C.; Alexandrou, Andreas N. (2009)
      The objective of this work is to study quantitatively the errors introduced by the standard Newtonian and power-law assumptions used in the determination of the material properties of viscoplastic fluids from circular ...
