Numerical investigation of the small scales in a jet
The focus of this investigation is on the isotropy of small scales in aturbulent jet. The
aim is to get a better understanding of the structures in the jet and to see
wether scale similarity arguments can be employed for LES modelling. Therefore
the invariants of the anisotropy tensor are used and a new variable is
introduced which measures the departure from isotropy
and is used to visualize the results.
