Investigating the Linear Dynamics of the Near-Field of a Turbulent High-Speed Jet Using Dual-Particle Image Velocimetry (PIV) and Dynamic Mode Decomposition (DMD)

open access: yesFluids, 2023
The quest for the physical mechanisms underlying turbulent high-speed jet flows is underpinned by the extraction of spatio-temporal coherent structures from their flow fields.

Variability of Internally Generated Turbulence in an Estuary, from 100 Days of Continuous Observations [PDF]

open access: yes, 2009
We present detailed observations of internally generated turbulence in a sheared, stratified natural flow, as well as an analysis of the external factors leading to its generation and temporal variability.

Physics-informed machine learning approach for augmenting turbulence models: A comprehensive framework [PDF]

open access: yesPhysical Review Fluids, 2017
We present a comprehensive framework for augmenting turbulence models with physics-informed machine learning, illustrating a complete workflow from identification of input/output to prediction of mean velocities. The learned model has Galilean invariance

POD Analysis of the Wake of Two Tandem Square Cylinders

open access: yesFluids
This study aims to investigate the wake of two tandem square cylinders based on the Proper Orthogonal Decomposition (POD) analyses of the PIV and hotwire data. The cylinder centre-to-centre spacing ratio L/w examined is from 1.2 to 4.2, covering the four

Numerical Studies of Quantum Turbulence [PDF]

open access: yesJ. Low. Temp. Phys. 188, 119 (2017), 2017
We review numerical studies of quantum turbulence. Quantum turbulence is currently one of the most important problems in low temperature physics and is actively studied for superfluid helium and atomic Bose--Einstein condensates. A key aspect of quantum turbulence is the dynamics of condensates and quantized vortices. The dynamics of quantized vortices

Turbulent jet interaction with a long rise-time pressure signature [PDF]

open access: yes, 2016
A sonic boom signature with a long rise time has the ability to reduce the sonic boom, but it does not necessarily minimize the sonic boom at the ground level because of the real atmospheric turbulence.

Transitional–turbulent spots and turbulent–turbulent spots in boundary layers [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Significance Uncovering the constitutive coherent structure in the inner layer of the canonical turbulent boundary layer has remained a central fluid mechanics theme, because it tests our intellectual ability to understand even the simplest external flow.

A symmetry-based length model for characterizing the hypersonic boundary layer transition on a slender cone at moderate incidence

open access: yesAdvances in Aerodynamics, 2022
The hypersonic boundary layer (HBL) transition on a slender cone at moderate incidence is studied via a symmetry-based length model: the SED-SL model. The SED-SL specifies an analytic stress length function (which defines the eddy viscosity) describing a

The Nature of Subproton Scale Turbulence in the Solar Wind

open access: yes, 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.
