Dynamic Triad Interactions and Evolving Turbulence -- Part 2: Implications for Practical Signals
Preben Buchhave, Clara Velte
We investigate how momentum and kinetic energy is transferred between Fourier components (the so-called triad interactions) in measured turbulent flow fields, i.e. in practical, di…

Exact second-order spatio-temporal structure-function relationships in non-stationary incompressible turbulent flows with Reynolds decomposition and phase averaging
Yisheng Zhang, Clara M. Velte
The Karman-Howarth-Monin-Hill (KHMH) equation has been widely applied to scale-by-scale turbulent energy cascade studies in recent years, however, the forms and interpretations are…
