Mitigating adjoint chaos in wall turbulence
Qi Wang, Tamer A. Zaki
Estimating past events in wall turbulence based solely on surface measurements and first principles is an ill-posed problem that is complicated by chaos. The sensitivity of a measu…

Lagrangian Finite-Time Fluctuation Relation in isotropic turbulence
Hanxun Yao, Tamer A. Zaki, Charles Meneveau
The entropy generation rate in turbulence can be defined using the energy cascade rate as described in the scale-integrated Kolmogorov-Hill equation at a specified length scale. Th…

Analysis of inertial-range intermittency in forward and inverse cascade regions in isotropic turbulence
H. Yao, M. Schnaubelt, A. Lubonja +10
In order to test the hypothesis that inverse cascade regions in turbulent flows might exhibit more Gaussian noise-like and less intermittent small-scale statistics compared to the…
