Turbulence kinetic energy dissipation rates estimated from concurrent UAV and MU radar measurements
Earth, Planets and Space, 2018 We tested models commonly used for estimating turbulence kinetic energy dissipation rates $$\varepsilon$$ε from very high frequency stratosphere–troposphere radar data.

Phenomenology of buoyancy-driven turbulence: recent results
New Journal of Physics, 2017 In this paper, we describe the recent developments in the field of buoyancy-driven turbulence with a focus on energy spectrum and flux. Scaling and numerical arguments show that the stably-stratified turbulence with moderate stratification has kinetic ...

ION KINETIC ENERGY CONSERVATION AND MAGNETIC FIELD STRENGTH CONSTANCY IN MULTI-FLUID SOLAR WIND ALFVÉNIC TURBULENCE [PDF]
, 2015 We investigate the properties of plasma fluid motion in the large-amplitude, low-frequency fluctuations of highly Alfvénic fast solar wind. We show that protons locally conserve total kinetic energy when observed from an effective frame of reference ...

Deep-sea turbulence evolution observed by multiple closely spaced instruments
Scientific Reports, 2021 Turbulent mixing in the deep ocean is not well understood. The breaking of internal waves on sloped seafloor topography can generate deep-sea turbulence.

Turbulent kinetic energy in normal and myopathic left ventricles
Journal of Magnetic Resonance Imaging, 2014 PurposeTo assess turbulent kinetic energy (TKE) within the left ventricle (LV) of healthy subjects using novel 4D flow magnetic resonance imaging (MRI) methods and to compare TKE values to those from a limited group of patients with a spectrum of dilated cardiomyopathy (DCM).Materials and Methods4D flow and morphological MRI data were acquired in 11 ...

Implicit large eddy simulations of anisotropic weakly compressible turbulence with application to core-collapse supernovae [PDF]
, 2015 (Abridged) In the implicit large eddy simulation (ILES) paradigm, the dissipative nature of high-resolution shock-capturing schemes is exploited to provide an implicit model of turbulence.

The Nature of Subproton Scale Turbulence in the Solar Wind
, 2013 The nature of subproton scale fluctuations in the solar wind is an open question, partly because two similar types of electromagnetic turbulence can occur: kinetic Alfven turbulence and whistler turbulence.

Direct Energy Cascade in Two-Dimensional Compressible Quantum Turbulence [PDF]
, 2010 We numerically study two-dimensional quantum turbulence with a Gross--Pitaevskii model. With the energy initially accumulated at large scale, quantum turbulence with many quantized vortex points is generated.

A new dynamic subgrid-scale model using artificial neural network for compressible flow
Theoretical and Applied Mechanics Letters, 2022 The subgrid-scale (SGS) kinetic energy has been used to predict the SGS stress in compressible flow and it was resolved through the SGS kinetic energy transport equation in past studies.
