      Cessation of viscoplastic Poiseuille flow in a square duct with wall slip 

      Damianou, Y.; Kaoullas, G.; Georgiou, Georgios C. (2015)
      We solve numerically the cessation of the pressure-driven Poiseuille flow of a Bingham plastic under the assumption that slip occurs along the wall following a generalized Navier-slip law involving a non-zero slip yield ...

      Newtonian flow in a triangular duct with slip at the wall 

      Georgiou, Georgios C.; Kaoullas, G. (2013)
      We consider the Newtonian Poiseuille flow in a tube whose cross-section is an equilateral triangle. It is assumed that boundary slip occurs only above a critical value of the wall shear stress, namely the slip yield stress. ...

      Viscoplastic Poiseuille flow in a rectangular duct with wall slip 

      Damianou, Y.; Georgiou, Georgios C. (2014)
      We solve numerically the Poiseuille flow of a Herschel-Bulkley fluid in a duct of rectangular cross section under the assumption that slip occurs along the wall following a slip law involving a non-zero slip yield stress. ...
