Transitions of turbulent superstructures in generalized Kolmogorov flow
Cristian C. Lalescu, Michael Wilczek
Self-organized large-scale flow structures occur in a wide range of turbulent flows. Yet, their emergence, dynamics, and interplay with small-scale turbulence are not well understo…
Persistent accelerations disentangle Lagrangian turbulence
Lukas Bentkamp, Cristian C. Lalescu, Michael Wilczek
Particles in turbulence frequently encounter extreme accelerations between extended periods of quiescence. The occurrence of extreme events is closely related to the intermittent s…
Bias in particle tracking acceleration measurement
John M. Lawson, Eberhard Bodenschatz, Cristian C. Lalescu +1
We investigate sources of error in acceleration statistics from Lagrangian Particle Tracking (LPT) data and demonstrate techniques to eliminate or minimise bias errors introduced d…
How tracer particles sample the complexity of turbulence
Cristian C. Lalescu, Michael Wilczek
On their roller coaster ride through turbulence, tracer particles sample the fluctuations of the underlying fields in space and time. Quantitatively relating particle and field sta…
Patterns in the sine map bifurcation diagram
Cristian Constantin Lalescu
Numerical computations of bifurcation maps for one dimensional maps show patterns (regular jumps in point density) in the zones of chaotic behaviour. In this work, empiric formulas…
