Torsional parallel plate flow of Herschel-Bulkley fluids with wall slip
Evgenios Gryparis, Georgios C. Georgiou
The effect of wall slip on the apparent flow curves of viscoplastic materials obtained using torsional parallel plate rheometers is analysed by considering Herschel-Bulkley fluids…
Numerical solution of the Newtonian plane Couette flow with linear dynamic wall slip
Muner M. A. Hasan, Ethar A. A. Ahmed, Ahmed F. Ghaleb +2
An efficient numerical approach based on weighted average finite differences is used to solve the Newtonian plane Couette flow with wall slip, obeying a dynamic slip law that gener…
Analytical solution of the Poiseuille flow of a De Kee viscoplastic fluid
Alexandros Syrakos, Aggelos Charalambous, Georgios C. Georgiou
We provide an explicit analytical solution of the planar Poiseuille flow of a viscoplastic fluid governed by the constitutive equation proposed by De Kee and Turcotte (Chem. Eng. C…
Rheological characterization of a thixotropic semisolid slurry by means of numerical simulations of squeeze flow experiments
Georgios C. Florides, Georgios C. Georgiou, Michael Modigell +1
We propose a methodology for the rheological characterization of a semisolid metal slurry using experimental squeeze flow data. The slurry is modeled as a structural thixotropic vi…
