Understanding how granular flows interact with obstacles is important in the design of
mitigation measures for avalanches and other geophysical hazards. Such measures often …

We present the results of an experimental study of granular segregation on a large number
of rectangular grain piles built by dropping simultaneously glass beads of two different sizes …

In this paper, we study the transport of particles through a porous structure. Experimentally,
we focus our attention on the dependence of the mean transit time on some parameters like …

We investigate the effect of a forest of pillars on a granular layer steadily flowing over a
rough inclined plane. We quantify experimentally how the steady flow rate of grains is …

The dynamics of segregation, mixing and layering is studied during the build-up of quasi-2D
piles of two different species of grains of different diameters (ie 1 mm glass beads and either …

In 1873 Francis Galton had constructed a simple mechanical device where a ball is dropped
vertically through a harrow of pins that deflect the ball sideways as it falls. Galton called the …

A Galton board, also known as a quincunx, is a device invented by Francis Galton in 1873
that consists of two upright boards with rows of pins, and a funnel. In this paper, three new …

The Galton board is a classical device demonstrating geometrically the formation of normal
distributions. In view of long-range interactions, governed by nonextensive statistics, the …

Here we present an experimental and numerical study concerning the problem of the
influence of walls on a granular flow through obstacles. The system based on a Galton …

A Galton board is an instrument invented in 1873 by Francis Galton (1822–1911). It is a box
with a glass front and many horizontal nails or pins embedded in the back and a funnel …
