Project

Experimental study of organized structures in turbulent boundary layer with free-stream turbulence (GA15-18964S)

description based on the coherent structures detection. Investigation of dynamical phenomena of the coherent structures will help us to estimate energy and momentumUnderstanding special features of turbulence...

PARADOX OF HELICAL INSTABILITIES (IAA200760705)

The aim is to study origin, development and mutual interaction of instabilities in flowing fluids - and the corresponding coherent structures - having helical character and chirality (left- or right-handedness). They exhibit unique ...
