On Grid-Generated Quantum Turbulence [PDF]
EntropyNearly homogeneous and isotropic turbulence, generated in flows through grids of various forms in wind tunnels or by towing or oscillating grids in stationary samples of classical viscous fluids and the superfluid phases of helium, have played an ...

Design of an accessible turbulence chamber for laboratory experiments [PDF]
HardwareXHomogeneous isotropic turbulence (HIT) chambers provide a valuable platform for experimentally studying turbulence across a wide range of systems. Existing designs are often characterized by high cost, complex fabrication requirements, and reliance on ...

High-fidelity database of supercritical homogeneous isotropic turbulence in the pseudo-boiling region [PDF]
Scientific DataSupercritical fluids operate above their critical point and are characterized by strong nonlinearities in the equation of state, highly non-ideal fluid behavior, and a tight coupling between thermodynamics and transport properties.

Liutex-Represented Vortex Spectrum in Turbulence
Entropy, 2022 The Liutex vector is new quantity introduced to represent the rigid-body rotation part of fluid motion and thus to define and identify vortices in various flows. In this work, the intermittency and power-law similarity of the Liutex vector in homogeneous,

The spatio-temporal spectrum of turbulent flows [PDF]
, 2015 Identification and extraction of vortical structures and of waves in a disorganised flow is a mayor challenge in the study of turbulence. We present a study of the spatio-temporal behavior of turbulent flows in the presence of different restitutive ...

Energy transfer and vortex structures: visualizing the incompressible turbulent energy cascade
New Journal of Physics, 2023 The transfer of kinetic energy from large to small scales is a hallmark of turbulent flows. Yet, a precise mechanistic description of this transfer, which is expected to occur via an energy cascade, is still missing.

Energies, 2020 Wind turbines are usually clustered in wind farms which causes the downstream turbines to operate in the turbulent wakes of upstream turbines. As turbulence is directly related to increased fatigue loads, knowledge of the turbulence in the wake and its ...

Floc Size Distributions of Cohesive Sediment in Homogeneous Isotropic Turbulence
Frontiers in Earth Science, 2022 Floc size distribution is one of the key parameters to characterize flocculating cohesive sediment. An Eulerian–Lagrangian framework has been implemented to study the flocculation dynamics of cohesive sediments in homogeneous isotropic turbulent flows ...
