We consider the current state of our understanding of the rheology of two-phase magmas,
that is suspensions of either bubbles or crystals in a viscous silicate melt. The discussion is …

The style and evolution of volcanic eruptions are dictated by the fluid mechanics governing
magma ascent. Decompression during ascent causes dissolved volatile species, such as …

Over the past 25 years, our understanding of the physical processes that drive volcanic
eruptions has increased enormously thanks to major advances in computational and …

Technical and environmental concerns, besides water conservation in remote areas, are
associated with the utilization of conventional water, oil, and polymer based fracturing …

Aqueous foam can be used as a transfer medium to form lightweight materials from natural
and man-made fibers together with other types of raw materials. This review discusses …

When considering the rheology of a suspension the fundamental physical aspect to be
quantified is the redistribution of strain between the deformable matrix fraction of the …

The injection of gas bubbles into a turbulent boundary layer of a liquid phase has multiple
different impacts on the original flow structure. Frictional drag reduction is a phenomenon …

The eruptive dynamics of volcanic systems are largely controlled by the viscosity of
deforming magma. Here we report the results of a series of high-temperature, high-pressure …

Rhyolite magma has fuelled some of the Earth's largest explosive volcanic eruptions. Our
understanding of these events is incomplete, however, owing to the previous lack of directly …

Volcanoes emit larger amounts of volcanic gas than can be dissolved in the volume of
erupted magma during a variety of volcanic processes, including explosive and effusive …
