Chemical turbulence equivalent to Nikolavskii turbulence [PDF]

Physical Review E, 2004
We find evidence that a certain class of reaction-diffusion systems can exhibit chemical turbulence equivalent to Nikolaevskii turbulence. The distinctive characteristic of this type of turbulence is that it results from the interaction of weakly stable ...

POD Analysis of the Wake of Two Tandem Square Cylinders

Fluids
This study aims to investigate the wake of two tandem square cylinders based on the Proper Orthogonal Decomposition (POD) analyses of the PIV and hotwire data. The cylinder centre-to-centre spacing ratio L/w examined is from 1.2 to 4.2, covering the four

A computational framework for physics-informed symbolic regression with straightforward integration of domain knowledge

Scientific Reports, 2023
Discovering a meaningful symbolic expression that explains experimental data is a fundamental challenge in many scientific fields. We present a novel, open-source computational framework called Scientist-Machine Equation Detector (SciMED), which ...

Protecting entanglement of twisted photons by adaptive optics

, 2018
We study the efficiency of adaptive optics (AO) correction for the free-space propagation of entangled photonic orbital-angular-momentum (OAM) qubit states, to reverse moderate atmospheric turbulence distortions.

Multi-scale analysis of turbulence evolution in the density stratified intracluster medium

, 2018
The diffuse hot medium inside clusters of galaxies typically exhibits turbulent motions whose amplitude increases with radius, as revealed by cosmological hydrodynamical simulations. However, its physical origin remains unclear. It could either be due to

Strong Universality in Forced and Decaying Turbulence

, 2003
The weak version of universality in turbulence refers to the independence of the scaling exponents of the $n$th order strcuture functions from the statistics of the forcing.

Passing-over leading-edge vortex: The thrust booster in heaving airfoil

AIP Advances, 2019
The thrust generated by heaving airfoil in incompressible flow is studied both numerically and theoretically. It is found that the behaviors of leading-edge vortex (LEV) under different airfoil’s transverse velocities have an important influence on the ...

Turbulence Intensity Scaling: A Fugue

, 2019
We study streamwise turbulence intensity definitions using smooth- and rough-wall pipe flow measurements made in the Princeton Superpipe. Scaling of turbulence intensity with the bulk (and friction) Reynolds number is provided for the definitions.
