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 …

The flows of fluid via sudden expansions are among the basic topics within the discipline of
fluid mechanics. The comprehension of these types of flows has attracted a great volume of …

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 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 …

Abstract Anywhere between 0% and 80% of primary cemented wells have integrity failures.
Strong local variability suggests both geological and operational factors. One way geology …

Pipe annular cavities are present in equipment related to the oil and gas and other process
industries. The flow in a pipe initially expands into an annular cavity of a given length with a …

Slow flows of Bingham fluids through wavy-walled channels have stationary fouling layers if
the amplitude of the wall perturbation h exceeds some critical value hf. We have …

The dynamics of a single elastoviscoplastic drop immersed in plane shear flow of a
Newtonian fluid is studied by three-dimensional direct numerical simulations using a finite …

In the context of both production and well abandonment, effective cementing of the surface
casing is key in preventing leakage of formation fluids. Although there are general …
