Multi-scale analysis of turbulence evolution in the density stratified intracluster medium

, 2018
The diffuse hot medium inside clusters of galaxies typically exhibits turbulent motions whose amplitude increases with radius, as revealed by cosmological hydrodynamical simulations. However, its physical origin remains unclear. It could either be due to

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)

Fluids, 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.

Strong Universality in Forced and Decaying Turbulence

, 2003
The weak version of universality in turbulence refers to the independence of the scaling exponents of the $n$th order strcuture functions from the statistics of the forcing.

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.

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

Advances 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

A computational framework for physics-informed symbolic regression with straightforward integration of domain knowledge

Scientific Reports, 2023
Discovering a meaningful symbolic expression that explains experimental data is a fundamental challenge in many scientific fields. We present a novel, open-source computational framework called Scientist-Machine Equation Detector (SciMED), which ...

Passing-over leading-edge vortex: The thrust booster in heaving airfoil

AIP Advances, 2019
The thrust generated by heaving airfoil in incompressible flow is studied both numerically and theoretically. It is found that the behaviors of leading-edge vortex (LEV) under different airfoil’s transverse velocities have an important influence on the ...
