Turbulent fountains are of major interest for many natural phenomena and industrial
applications, and can be considered as one of the canonical examples of turbulent flows …

Turbulent negatively buoyant jets occur when the buoyancy of a jet directly opposes its
momentum, and will decelerate until its mean momentum is reduced to zero. Here, the flow …

A fundamental study has been conducted to understand the mean and turbulence
characteristics and their role in mixing processes of starting turbulent plumes initiated by a …

Tephra deposits retain a considerable amount of information about the nature of volcanic
eruptions, with plume height commonly inferred from maximum clast size measurements …

Meaningful forecasting of the atmospheric concentration and ground accumulation of
volcanic ash during explosive eruptions requires detailed knowledge of the eruption source …

Efficient turbulent entrainment causes otherwise dense volcanic jets to rise high into the
atmosphere as buoyant plumes. Classical models suggest that the inflow of air is 10–15% of …

We present a coupled fluid-dynamic and electromagnetic model for volcanic ash plumes. In
a forward approach, the model is able to simulate the plume dynamics from prescribed input …

Fast fluid dynamics (FFD) is an intermediate model between multi-zone models and
computational fluid dynamics (CFD) models for indoor airflow simulations. The use of coarse …

Tephra transport modelling has predominantly been carried out over synoptic-scale
resolutions, resolving only fundamental atmospheric circulations. Consequently, model …

We review techniques for measuring fluid flow and advective heat output from seafloor
hydrothermal systems and describe new anemometer and turbine flowmeter devices we …
