Stochastic Lagrangian Dynamics of Vorticity. II. Channel-Flow Turbulence
Gregory L. Eyink, Akshat Gupta, Tamer Zaki
We here exploit a rigorous mathematical theory of vorticity dynamics for Navier-Stokes solutions in terms of stochastic Lagrangian flows and their stochastic Cauchy invariants, tha…
Stochastic Lagrangian Dynamics of Vorticity. I. General Theory
Gregory L. Eyink, Akshat Gupta, Tamer Zaki
Prior mathematical work of Constantin and Iyer (2008, 2011) has shown that incompressible Navier-Stokes solutions possess infinitely-many stochastic Lagrangian conservation laws fo…
Data compression for turbulence databases using spatio-temporal sub-sampling and local re-simulation
Zhao Wu, Tamer A. Zaki, Charles Meneveau
Motivated by specific data and accuracy requirements for building numerical databases of turbulent flows, data compression using spatio-temporal sub-sampling and local re-simulatio…
The mean conformation tensor in viscoelastic turbulence
Ismail Hameduddin, Tamer A. Zaki
This work demonstrates that the popular arithmetic mean conformation tensor frequently used in the analysis of turbulent viscoelastic flows is not a good representative of the ense…
