Anomalous Scaling and Structure Instability in Three-Dimensional Passive Scalar Turbulence
Shiyi Chen, Nianzheng Cao
The anomalous scaling phenomena of three-dimensional passive scalar turbulence are studied using high resolution direct numerical simulation. The inertial range scaling exponents o…
An Intermittency Model For Passive-Scalar Turbulence
Nianzheng Cao, Shiyi Chen
A phenomenological model for the inertial range scaling of passive-scalar turbulence is developed based on a bivariate log-Poisson model. An analytical formula of the scaling expon…
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…
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…
