The dynamics of explosive volcanic eruptions

AW Woods - Reviews of geophysics, 1995 - Wiley Online Library
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 …

[图书][B] Suspension acoustics: An introduction to the physics of suspensions

On the vesicularity of pumice

N Thomas, C Jaupart… - Journal of Geophysical …, 1994 - Wiley Online Library
We develop a physical framework for the evolution of vesicular magma fragments after their
formation by fragmentation in explosive eruptions. These fragments are carried by a …

Nonequilibrium flow in volcanic conduits and application to the eruptions of Mt. St. Helens on May 18, 1980, and Vesuvius in AD 79

F Dobran - Journal of Volcanology and Geothermal Research, 1992 - Elsevier
A steady-state, one-dimensional, and nonhomogeneous two-phase flow model was
developed for the prediction of local flow properties in volcanic conduits. The model …

The decompression of volcanic jets in a crater during explosive volcanic eruptions

AW Woods, SM Bower - Earth and Planetary Science Letters, 1995 - Elsevier
During explosive volcanic eruptions, fragmented silicic magma and volatiles exit the vent
with pressures typically in the range 10–100 atm and at the speed of sound of the mixture …

Insights into volcanic conduit flow from an open‐source numerical model

LG Mastin - Geochemistry, Geophysics, Geosystems, 2002 - Wiley Online Library
Numerical models that calculate the fluid dynamics of explosive volcanic eruptions have
been used with increasing frequency to understand volcanic processes and evaluate …

Lunar magma transport phenomena
