Fluctuation-induced force in homogeneous isotropic turbulence. [PDF]
Sci Adv, 2020 We find an analog to the quantum Casimir effect in a turbulent fluid. Understanding force generation in nonequilibrium systems is a notable challenge in statistical physics.

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.

Thermal fluctuations in the dissipation range of homogeneous isotropic turbulence [PDF]
Journal of Fluid Mechanics, 2021 Using fluctuating hydrodynamics we investigate the effect of thermal fluctuations in the dissipation range of homogeneous isotropic turbulence. Simulations confirm theoretical predictions that the energy spectrum is dominated by these fluctuations at ...

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,
