Explosive volcanic eruptions involve the ejection of dense mixtures of ash and gas from a
volcanic vent at high speed and pressure. This mixture is generated as liquid magma rises …

The complexity of flow and wide variety of depositional processes operating in subaqueous
density flows, combined with post‐depositional consolidation and soft‐sediment …

This paper describes a model to predict the flow of an initially stationary mass of cohesion-
less granular material down rough curved beds. This work is of interest in connection with …

The article is a review of mathematical models of snow avalanches that have been proposed
since the middle of the 20th century and are still in use. The main attention is paid to the …

Results are presented from a high-resolution computational study of particle-driven gravity
currents in a plane channel. The investigation was conducted in order to obtain better insight …

Entrainment of ambient fluid into both two-dimensional and axisymmetric gravity currents is
investigated experimentally using a novel neutralization technique. The technique involves …

Using a set of large eddy point-particle simulations, we explore the fluid dynamics of an
ejected puff resulting from a cough/sneeze. The ejection contains over 61 000 potentially …

This paper is concerned with the motion of an unconfined finite mass of a granular material
released from rest on an inclined plane. The granular mass is treated as a frictional …

Observations of the flow of dense fluid into uniformly density-stratified environments down
plane slopes with small inclination to the horizontal ([les] 20°) are described, and a …

A self‐accelerating current is a particle‐driven gravity flow moving on a sloping bottom
whose velocity increases in the downstream direction as a result of increasing suspended …
