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…
Comparing local energy cascade rates in isotropic turbulence using structure function and filtering formulations
H. Yao, M. Schnaubelt, A. Szalay +2
Two common definitions of the spatially local rate of kinetic energy cascade at some scale in turbulent flows are (i) the cubic velocity difference term appearing in the gen…
Entropy and fluctuation relations in isotropic turbulence
H. Yao, T. A. Zaki, C. Meneveau
Based on a generalized local Kolmogorov-Hill equation expressing the evolution of kinetic energy integrated over spheres of size in the inertial range of fluid turbulence, w…
