This article offers a comprehensive overview of the underlying physics relevant to an
understanding of materials processing during the various production steps in extrusion …

Yield stress fluids are encountered in a wide range of applications: toothpastes, cements,
mortars, foams, muds, mayonnaise, etc. The fundamental character of these fluids is that …

Yield stress fluid flows occur in a great many operations and unit processes within the oil
and gas industry. This paper reviews this usage within reservoir flows of heavy oil, drilling …

Recent years have seen a flurry of research on yield stress fluids, approached from different
perspectives (physicochemical, rheological and fluid mechanical), considering different …

I present an alternative reasoning for the choice of characteristic quantities to be employed
in the non-dimensionalization of the governing equations of non-Newtonian fluid flow …

Yield stress materials are known to possess a certain threshold property, a strength, that
must be overcome in order for flow to occur. This strength is commonly conceived as a …

In this paper, a three‐dimensional numerical solver is developed for suspensions of rigid
and soft particles and droplets in viscoelastic and elastoviscoplastic (EVP) fluids. The …

We investigate the performance of the finite volume method in solving viscoplastic flows. The
creeping square lid-driven cavity flow of a Bingham plastic is chosen as the test case and …

We perform a detailed computational study of the flow of a Bingham fluid along a narrow
channel, with one locally uneven wall. This uneven section of the channel represents a …

We study steady inertial flows of a Bingham fluid through 2D “washout” geometries, that
represent longitudinal sections of an oil and gas well under construction, thus extending our …
