The effects of large scales on the inertial range in high-Reynolds-number turbulence
Katepalli R. Sreenivasan, Brindesh Dhruva, Inigo San Gil
The effects of removing large scales external to the inertial range on the properties of scales within the inertial range are studied in a high-Reynolds-number turbulent flow. Stru…
The Scaling Structure of the Velocity Statistics in Atmospheric Boundary Layer
Susan Kurien, Victor S. L'vov, Itamar Procaccia +1
The statistical objects characterizing turbulence in real turbulent flows differ from those of the ideal homogeneous isotropic model.They containcontributions from various 2d and 3…
The Extraction of Anisotropic Contributions in Turbulent Flows
Itai Arad, Brindesh Dhruva, Susan Kurien +3
We analyze turbulent velocity signals measured by two probes in the atmosphere, both at the height of 35 meters but displaced by 40 cm nominally orthogonal to the mean wind. Choosi…
A Refined Similarity Hypothesis for Transverse Structure Functions
Shiyi Chen, Katepalli R. Sreenivasan, Mark Nelkin +1
We argue on the basis of empirical data that Kolmogorov's refined similarity hypothesis (RSH) needs to be modified for transverse velocity increments, and propose an alternative. I…
Fusion Rules in Navier-Stokes Turbulence: First Experimental Tests
Adrienne L. Fairhall, Brindesh Dhruva, Victor S. L'vov +2
We present the first experimental tests of the recently derived fusion rules for Navier-Stokes (N-S) turbulence. The fusion rules address the asymptotic properties of many-point co…
Scaling of Low-Order Structure Functions in Homogeneous Turbulence
Nianzheng Cao, Shiyi Chen, Katepalli R. Sreenivasan
High-resolution direct numerical simulation data for three-dimensional Navier-Stokes turbulence in a periodic box are used to study the scaling behavior of low-order velocity struc…
