Thixotropic flow past a cylinder
(2014)
We study the flow of a thixotropic fluid around a cylinder. The rheology of the fluid is described by means of a structural viscoplastic model based on the Bingham constitutive equation, regularised using the Papanastasiou ...
Numerical study of the combined effects of inertia, slip, and compressibility in extrusion of yield stress fluids
(2014)
The axisymmetric extrudate swell flow of a compressible Herschel–Bulkley fluid with wall slip is solved numerically. The Papanastasiou-regularized version of the constitutive equation is employed, together with a linear ...
