Short-time evolution of Lagrangian velocity gradient correlations in isotropic turbulence

Article in Phys. Fluids (2015)

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 (...)
