      Combined effects of compressibility and slip in flows of a Herschel-Bulkley fluid 

      Damianou, Y.; Georgiou, Georgios C.; Moulitsas, I. (2013)
      In this work, the combined effects of compressibility and slip in Poiseuille flows of Herschel-Bulkley fluids are investigated. The density is assumed to obey a linear equation of state, and wall slip is assumed to follow ...

      Development of confined viscoplastic flows with heterogeneous wall slip 

      Panaseti, Pandelitsa; Philippou, Maria; Kountouriotis, Zacharias; Georgiou, Georgios C. (National Technical University of Athens, 2016)
      The steady, pressure-driven flow of a Herschel-Bulkley fluid in a channel is considered assuming that slip occurs on one wall only due to slip heterogeneities. Hence, the velocity profile is allowed to be asymmetric. The ...

      Newtonian Poiseuille flows with pressure-dependent wall slip 

      Panaseti, Pandelitsa; Housiadas, Kostas D.; Georgiou, Georgios C. (2013)
      The effect of pressure-dependent slip at the wall in steady, isothermal, incompressible Poiseuille flows of a Newtonian liquid is investigated. Exponential dependence of the slip coefficient on the pressure is assumed and ...

      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 ...

      Viscoplastic flow development in a channel with slip along one wall 

      Panaseti, Pandelitsa; Georgiou, Georgios C. (2017)
      The flow development of a Herschel–Bulkley fluid in a horizontal channel is considered assuming that slip occurs only on the upper wall due to slip heterogeneities. Hence, the velocity profile is allowed to be asymmetric ...

      Viscoplastic flow development in tubes and channels with wall slip 

      Philippou, Maria; Kountouriotis, Zacharias; Georgiou, Georgios C. (2016)
      The development of Bingham plastic flow in tubes and channels is investigated numerically using the Papanastasiou regularization and finite element simulations. It is assumed that slip occurs along the wall following ...
