GALLERY : Turbulence - Plane Jet



 << back

 

 

Spatially developing plane jet obtained by direct numerical simulation (DNS) with a mesh of 130 million points. Re = 3000. The first video shows the transport of a passive scalar done by a plane jet. The second video show the iso-countours of the Q-criteria. In both cases, the post-processing was done with Paraview.

This videos resulted from the work done for three publications:

 

The role of coherent vortices near the turbulent/non-turbulent interface in a planar jet

 

The intense vorticity structures near the turbulent/nonturbulent interface in a jet

 

The thickness of the turbulent/nonturbulent interface is equal to the radius of the large vorticity structures near the edge of the shear layer
