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 ...

Physical Review X, 2021 Never is the difference between thermal equilibrium and turbulence so dramatic, as when a quadratic invariant makes the equilibrium statistics exactly Gaussian with independently fluctuating modes. That happens in two very different yet deeply connected classes of systems: incompressible hydrodynamics and resonantly interacting waves.

Stirring turbulence with turbulence [PDF]
Physics of Fluids, 2015 We stir wind-tunnel turbulence with an active grid that consists of rods with attached vanes. The time-varying angle of these rods is controlled by random numbers. We study the response of turbulence on the statistical properties of these random numbers.

Turbulent Firms, Turbulent Wages? [PDF]
SSRN Electronic Journal, 2006 Has greater turbulence among firms fueled rising wage instability in the United States? Earlier research by Gottschalk and Moffitt shows that rising earnings instability was responsible for one-third to one-half of the rise in wage inequality during the 1980s. These growing transitory fluctuations remain largely unexplained. To help fill this gap, this

Is 2D turbulence a conformal turbulence? [PDF]
Physical Review Letters, 1993 A critical analysis of the conformal approach to the theory of 2d turbulence is delivered. It is shown, in particular, that conformal minimal models cannot give a general turbulent solution, which should provide for constant fluxes of all vorticity integrals of motion.

Cleaner Engineering and Technology, 2022 The shape design for a thermoelectric generator (TEG) plays an important role in its performance. In this paper, a hyperbolic function was introduced to design a variable cross-section TEG module to optimize the configuration for maximum power generation

Numerical Simulation on the Scalar Transport in Rotating Channel Turbulence
气体物理, 2023 Passive scalar transport in channel turbulence with spanwise rotation is of relevance to many engineering applications. A systematical study on this problem was conducted based on direct numerical simulations. The Reynolds number defined by wall-friction
