Data-driven theoretical modelling of the turbulent energy cascade
… gewinnt man wertvolle Einsichten in die Dynamik turbulenter Strömungen. In dieser Arbeit werden multiplikative Kaskadenprozesse untersucht und mit verschiedenen experimentellen Zeitreihen der Energiedissipation verglichen. Zur Berechnung der Energiedissipation ist es unvermeidlich auf eine …

Causal inference for complex systems and applications to turbulent flows
… the applicability of our approach in two turbulent-flow scenarios: the energy transfer across scales in the turbulent energy cascade and the interaction between motions across scales in a turbulent boundary layer. Our results show that, without accounting for redundant and synergistic …

Numerical study on internal flow structures of subaqueous density underflows and stratified open-channel flows
… to the inability of the RANS models to describe energy dissipation due to internal waves, a mechanism substantially different from the turbulent energy cascade theory. Analyses showed that the dimensionless settling velocity and shear Richardson number are the most dominant dimensionless …

Data Analysis of an Unsteady Cavitating Flow on a Venturi-type Profile
… from the instabilities suggests a transfer of energy from the largest scales, fluctuating mean flow, to the smaller scales such as cloud cavitation and Kelvin-Helmholtz (KH) instability. It is demonstrated that the POD decorrelation of length scales yields inherently quasi-periodic time …
