Short-time evolution of Lagrangian velocity gradient correlations in isotropic turbulence
Le Fang, Wouter J. T. Bos & Guodong D. Jin
We show by direct numerical simulation (DNS) that the Lagrangian cross correlation of velocity gradients in homogeneous isotropic turbulence increases at short times, whereas its auto-correlation (...)
