3-D flow of Herschel-Bulkley fluids
(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. ...
Solution of viscoplastic flows with the finite volume / multigrid method
(National Technical University of Athens, 2013)
We investigate the performance of the finite volume method in solving viscoplastic flows. The square lid-driven cavity flow of a Bingham plastic is chosen as the test case and the constitutive equation is regularised as ...
