      3-D flow of Herschel-Bulkley fluids 

      Burgos, Gilmer R.; Alexandrou, Andreas N. (ASME, 1998)
      The flow of Herschel-Bulkley fluids through a sudden 3-D square with expansion height ratio of 2:1 is studied numerically by solving the mass and momentum conservation equations along with a continuous constitutive relation. ...

      Flow instabilities of Herschel-Bulkley fluids 

      Alexandrou, Andreas N.; Menn, P. Le; Georgiou, G.; Entov, V. (2003)
      We investigate numerically the interactions of two-dimensional jets of Bingham plastic and Herschel-Bulkley fluids with a vertical surface at a distance from the die exit. This problem simulates the early stages of filling ...

      Injection molding of dilute and semi-dilute fiber suspensions 

      Alexandrou, Andreas N.; Ahmed, Alauddin (Publ by ASME, 1992)
      The focus of this paper is unsteady flow of semi-dilute fiber suspensions in complex geometries. These flows are typical of injection molding problems in which the raw material in granular form, usually plastic resin mixed ...

      Processing of semi-solid materials using a shear-thickening Bingham fluid model 

      Ahmed, Alauddin; Alexandrou, Andreas N. (Publ by ASME, 1994)
      Recently the importance of processing metals and metal matrix composites in semi-solid state is growing rapidly. Performing the shape making operations in the semi-solid state provides a better opportunity to control the ...

      Unsteady flow of semi-concentrated suspensions using finite deformation tensors 

      Ahmed, A.; Alexandrou, Andreas N. (1994)
      The interest in the theoretical investigation of the flow behavior of fiber suspensions during manufacturing processes has increased considerably due to the increased interest in the use of composite materials. The unsteady ...
