The archetypal feature of a viscoplastic fluid is its yield stress: If the material is not sufficiently
stressed, it behaves like a solid, but once the yield stress is exceeded, the material flows like …

Viscoplasticity is characterized by a yield stress, below which the materials will not deform
and above which they will deform and flow according to different constitutive relations …

Numerical simulations of viscoplastic fluid flows have provided a better understanding of
fundamental properties of yield stress fluids in many applications relevant to natural and …

Consequences of submarine landslides include both their direct impact on offshore
infrastructure, such as subsea electric cables and gas/oil pipelines, and their indirect impact …

Water and air behave in a similar way and their flow can be described in a very accurate
way by the Navier–Stokes equations. Others fluids behave differently: they cannot be …

This paper presents an overview of depth averaged modelling of fast catastrophic landslides
where coupling of solid skeleton and pore fluid (air and water) is important. The first goal is …

Suspensions filled with rigid particles at volume-loading levels that approach their maximum
packing fraction are widely encountered, especially in the energetics, ceramics …

Plane Poiseuille flow of a Bingham fluid in a channel armed with a superhydrophobic (SH)
lower wall is analysed via a semi-analytical model, accompanied by complementary direct …

For the first time, a Newton method is proposed for the unregularized viscoplastic fluid flow
problem. It leads to a superlinear convergence for Herschel–Bulkley fluids when 0< n< 1 …

We solve numerically the cessation of axisymmetric Poiseuille flow of a Herschel–Bulkley
fluid under the assumption that slip occurs along the wall. The Papanastasiou regularization …
