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.

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

Urban water supply systems’ resilience under earthquake scenario
Scientific Reports, 2022 Threats to water supply systems have increased in number and intensity. Natural disasters such as earthquakes have caused different types of damage to water distribution networks (WDN), particularly for those with aged infrastructure.

Intercomparison of In Situ Sensors for Ground-Based Land Surface Temperature Measurements
Sensors, 2020 Land surface temperature (LST) is a key variable in the determination of land surface energy exchange processes from local to global scales. Accurate ground measurements of LST are necessary for a number of applications including validation of satellite ...

Hybrid Computation of the Aerodynamic Noise Radiated by the Wake of a Subsonic Cylinder
Fluids, 2023 The noise radiated by the flow around a cylinder in the subcritical regime at ReD=1×104 and at a subsonic Mach number of M=0.5 is here studied. The aerodynamic sound radiated by a cylinder has been studied with a wide range of Reynolds numbers, but there

The energy- and flux budget theory for surface layers in atmospheric convective and stably stratified turbulence [PDF]
Physics of Fluids 34, 116602 (2022), 2021 The energy- and flux budget (EFB) turbulence closure theory for the atmospheric surface layers in convective and stably stratified turbulence has been developed using budget equations for turbulent energies and fluxes in the Boussinesq approximation. In the lower part of the surface layer in the atmospheric convective boundary layer (CBL), the rate of ...

Physical Review Letters, 2014 We construct turbulent black holes in asymptotically AdS_4 spacetime by numerically solving Einstein equations. Both the dual holographic fluid and bulk geometry display signatures of an inverse cascade with the bulk geometry being well approximated by the fluid/gravity gradient expansion.

Turbulence dynamics near a turbulent/non-turbulent interface [PDF]
Journal of Fluid Mechanics, 2012 AbstractThe characteristics of the boundary layer separating a turbulence region from an irrotational (or non-turbulent) flow region are investigated using rapid distortion theory (RDT). The turbulence region is approximated as homogeneous and isotropic far away from the bounding turbulent/non-turbulent (T/NT) interface, which is assumed to remain ...
