Figure 1. Partially averaged velocity field for a single phase plume. Left: two isosurfaces of radial velocity at 
(red) and 
(blue). Note the entrainment associated to negative values of 
along the plume stem below the trapping height and the formation of the lateral intrusion associated to positive values of radial velocity. Right: two isosurfaces of vertical velocity at 
(red) and 
. Note the plume top surrounded by a ring of downdrafts (in blue) and the formation of gravity waves (outer ring of positive 
).
Figure 2. Similar to above for a bubble plume. The presence of gas, characterized by the slip velocity, leads to a destratification across the entire water column and the formation of peeling regions above the main lateral intrusion.

About Alexandre Fabregat Tomàs
As a postdoctoral fellow at City University of New York, I am interested in everything related with the numerical simulation of heat and mass transport in turbulent flows.
