To date, the understanding of the role buoyancy plays in the entrainment process in
unstable configurations such as turbulent plumes remains incomplete. Towards addressing …

Various scaling relationships relate the height of volcanic plumes to eruptive source
conditions, atmospheric density stratification, turbulent entrainment, and wind stresses …

On the evolution of the plume function and entrainment in the near-source region of lazy plumes
Page 1 J. Fluid Mech. (2017), vol. 830, pp. 736–759. c Cambridge University Press 2017 …

We derive a new expression for the entrainment coefficient in a turbulent plume using an
equation for the squared mean buoyancy. Consistency of the resulting expression with …

We present simultaneous two-dimensional velocity and scalar measurements on a central
vertical plane in an axisymmetric pure turbulent plume. We use an edge-detection algorithm …

Predictions for the heights and downwind trajectories of volcanic plumes using integral
models are critical for the assessment of risks and climate impacts of explosive eruptions but …

Laboratory experiments were conducted to investigate the dynamics of oblique particle
cloud in stagnant water. Previous laboratory studies on vertically downward particle clouds …

The effects of system rotation on the turbulent dynamics of bubble plumes evolving in
stratified environments are numerically investigated by considering variations in both the …

The input flow of groundwater from the seabed to the coastal ocean, known as Submarine
Groundwater Discharge (SGD), has been only recently recognized as an important …

We consider the problem of the vertically upwards disposal of heavy brine sewage from a
two-dimensional diffuser in a lighter, homogeneous, motionless and shallow ambient sea …
