Functional Renormalization for Elastic Burgulence
Johannes Conrad, Martin Oberlack
We formulate elastic and elasto-inertial turbulence in the Martin-Siggia-Rose path-integral formalism and develop a systematic source-extended symmetry algorithm to derive Ward ide…

A data-driven approach for 2D vorticity PDF equations by a new conditional average estimation
Qian Huang, Simon Görtz, Paul Hollmann +3
We consider the statistics for the vorticity field in two-dimensional homogeneous isotropic turbulence (HIT). First, we exploit the invariance properties to derive dimensionally re…
