Pyroclastic Density Currents: State of the Art and Perspectives

Journal of Volcanology and Geothermal Research, 2014
Pyroclastic density currents (PDCs) are mixtures of two components, namely solid particles and fluid (gas) phase. They macroscopically behave as dense, multiphase gravity currents (flowing pyroclastic mixtures of particles and gas) immersed in a less dense, almost isotropic fluid (the atmosphere).

A Fast, Calibrated Model for Pyroclastic Density Currents Kinematics and Hazard

Journal of Volcanology and Geothermal Research, 2016
Abstract Multiphase flow models represent valuable tools for the study of the complex, non-equilibrium dynamics of pyroclastic density currents. Particle sedimentation, flow stratification and rheological changes, depending on the flow regime, interaction with topographic obstacles, turbulent air entrainment, buoyancy reversal, and other complex ...

Analogue modelling of pyroclastic density current deposition [PDF]

, 2010
A series of analogue flume experiments are used to investigate initiation, flow and deposition of static piles of polymict materials, the sorting during transport, and the three dimensional geometry of the resulting deposits. Sequential charges are used to investigate the effects and extent of reworking.
