Intermittency from instanton calculus at the transition to turbulence and fusion rules
Timo Schorlepp, Rainer Grauer
Understanding intermittency of turbulent systems from the underlying differential equations is an outstanding problem in fluid dynamics. Here, in the example of Burgers turbulence…
Relevance of instantons in Burgers turbulence
Tobias Grafke, Rainer Grauer, Tobias Schäfer +1
Instanton calculations are performed in the context of stationary Burgers turbulence to estimate the tails of the probability density function (PDF) of velocity gradients. These re…
Numerical study of impeller-driven von Karman flows via a volume penalization method
Sophia Kreuzahler, Daniel Schulz, Holger Homann +2
The von Karman flow apparatus produces a highly turbulent flow inside a cylinder vessel driven by two counter-rotating impellers. Over more than two decades, this experiment has be…
Structures and Lagrangian statistics of the Taylor-Green Dynamo
Holger Homann, Yannick Ponty, Giorgio Krstulovic +1
The evolution of a Taylor-Green forced magnetohydrodynamic (MHD) system showing dynamo activity is analyzed via direct numerical simulations. The statistical properties of the velo…
Clustering of passive impurities in MHD turbulence
H. Homann, J. Bec, H. Fichtner +1
The transport of heavy, neutral or charged, point-like particles by incompressible, resistive magnetohydrodynamic (MHD) turbulence is investigated by means of high-resolution numer…
An exact relation between Eulerian and Lagrangian velocity increment statistics
O. Kamps, R. Friedrich, R. Grauer
We present a formal connection between Lagrangian and Eulerian velocity increment distributions which is applicable to a wide range of turbulent systems ranging from turbulence in…
