Mystery of the cargo ships that sink when their cargo suddenly liquefies

Mystery of the cargo ships that sink when their cargo suddenly liquefies • The Conversation
<p>Think of a dangerous cargo and toxic waste or explosives might come to mind. But granular cargoes such as crushed ore and mineral sands are responsible for the loss of numerous ships every year. On average, ten “solid bulk cargo” carriers have been lost at sea each year for the last decade.

Solid bulk cargoes – defined as granular materials loaded directly into a ship’s hold – can suddenly turn from a solid state into a liquid state, a process known as liquefaction. And this can be disastrous for any ship carrying them – and their crew.

In 2015, the 56,000-tonne bulk carrier Bulk Jupiter rapidly sunk around 300km south-west of Vietnam, with only one of its 19 crew surviving. This prompted warnings from the International Maritime Organisation about the possible liquefaction of the relatively new solid bulk cargo bauxite (an aluminium ore).

A lot is known about the physics of the liquefaction of granular materials from geotechnical and earthquake engineering. The vigorous shaking of the earth causes pressure in the ground water to increase to such a level that the soil “liquefies”. Yet despite our understanding of this phenomenon, and the guidelines in place to prevent it occurring, it is still causing ships to sink and taking their crew with them.

Solid bulk cargoes are typically “two-phase” materials as they contain water between the solid particles. When the particles can touch, the friction between them makes the material act like a solid (even though there is liquid present). But when the water pressure rises, these inter-particle forces reduce and the strength of the material decreases. When the friction is reduced to zero, the material acts like a liquid (even though the solid particles are still present).

A solid bulk cargo that is apparently stable on the quayside can liquefy because pressures in the water between the particles build up as it is loaded onto the ship.</p>

There's a terrific part of the book The Martian which involves a similar calamity. The science of this is pretty scary: you wouldn't want to be on a ship with something thixotropic like this.

Dover Beach by Matthew Arnold | Poetry Foundation
The Sea of Faith
Was once, too, at the full, and round earth’s shore
Lay like the folds of a bright girdle furled.
But now I only hear
Its melancholy, long, withdrawing roar,
Retreating, to the breath
Of the night-wind, down the vast edges drear
And naked shingles of the world.

Ah, love, let us be true
To one another! for the world, which seems
To lie before us like a land of dreams,
So various, so beautiful, so new,
Hath really neither joy, nor love, nor light,
Nor certitude, nor peace, nor help for pain;
And we are here as on a darkling plain
Swept with confused alarms of struggle and flight,
Where ignorant armies clash by night.

How to Get More Out of Fluid « Mac.AppStorm
If you’re someone who dips in and out of several web apps on a daily basis, you may be interested to know that an application for OSX can make your life easier. Fluid allows you to create ‘Site Specific Browsers’ (SSBs) – a separate desktop app for each website you use on a regular basis.

Oztekin, Dennis Ekin, "The Lattice Boltzmann Methods and Their Applications to Fluid Flows" (2014). Theses and Dissertations. Paper 1581.
"The history of the Lattice Boltzmann Method and its application to fluid mechanics are
investigated here. Detailed formulations are provided to form a basis for the Lattice
Boltzmann Method and its many variations. These variations are designed to overcome
shortcomings in the standard single relaxation time Lattice Boltzmann model. Presented
here are: a model that utilizes the non-equilibrium parts of the stress tensor, the
Regularized Lattice Boltzmann model; a model that converts over to momentum space,
the Multi-Relaxation Time Lattice Boltzmann model; and a model that corrects itself
using the entropy equation, the entropic Lattice Boltzmann model. Extensions for the
Lattice Boltzmann method are derived that include: external forces, multiphase flows,
and thermal flows. Various types of boundary conditions are modeled using different
approaches. A detailed explanation on extracting common macroscopic flow properties in
physical units is provided. These extracted properties can be used to check temporal and
spatial convergence. A two dimensional, nine velocity model and a three dimensional,
fifteen velocity model are used to provide examples of a number of the approaches
mentioned. A two dimensional and three dimensional lid-driven cavity flow is used to
illustrate these methods. "
