TLDR
In this article, the authors investigate the high temperature (1131°C) of a basaltic volcano and investigate its behavior in terms of the textural evolution and rheological properties of eruptive products.About:

The rheology of two-phase magmas: A review and analysis
TL;DR: In this article, the authors present a new semi-empirical constitutive model for bubble-bearing suspensions, which is valid for steady and unsteady flow and large strains and strain-rates.

Silicic magma reservoirs in the Earth's crust
Olivier Bachmann,Christian Huber +1 more
TL;DR: In this article, the authors focus on recent claims that magma columns within the Earth's crust are mostly kept at high crystallinity (mush zones) and that the dynamics within those mush columns, albeit modulated by external factors (e.g., regional stress field, rheology of the crust, pre-existing tectonic structure), play an important role in controlling how magmas evolve, degas, and ultimately erupt.

Effects of crystal shape- and size-modality on magma rheology
P. Moitra,Helge M. Gonnermann +1 more
TL;DR: In this paper, a suite of shear viscosity measurements on liquid-particle suspensions of dynamical similarity to crystal-bearing magma was performed, and the results were fitted using a Herschel-Bulkley model and augment existing predictive capabilities.
Journal ArticleDOI
Rheology of magmas with bimodal crystal size and shape distributions: Insights from analog experiments
TL;DR: In this article, rotational rheometric methods are used to determine the rheology of monodisperse and polydisperse suspensions consisting of smaller, prolate particles (microlites) and larger, equant particles (phenocrysts) in a bubble-free Newtonian liquid (silicate melt).

Dynamics of Strombolian explosions: Inferences from field and laboratory studies of erupted bombs from Stromboli volcano

TL;DR: In this article, the authors investigated the role of a slug ascending too fast through a magma of varying viscosity and yield strength in the bubble-bursting process at Stromboli and found that fresh, microlite-poor, vesiculated batch experienced a response to the explosive event, by undergoing rapid decompression.

The motion of ellipsoidal particles immersed in a viscous fluid
TL;DR: In this article, the authors considered the case of particles of ellipsoidal shape, and showed that the condition for the validity of this approximation is that the product of the velocity of the ellipssoid by its linear dimensions shall be small compared with the "kinematic coefficient, of viscosity" of the fluid.
