Spanwise-coherent hydrodynamic waves around flat plates and airfoils
(2021-11-25)
We investigate spanwise-coherent structures in the turbulent flow around airfoils, motivated by their connection with trailing-edge noise. We analyse well-resolved large-eddy simulations (LES) of the flow around NACA 0012 ...
Dynamics of the large-scale structures and associated noise emission in airfoil slats
(Cambridge Univ Press, 2019-09-25)
We investigate the slat narrowband peak noise generating mechanism. Unsteady flow data were generated by a lattice-Boltzmann-based commercial code for four configurations, accounting for variations of the airfoil angle of ...
Noise and ultraviolet divergences in the dynamics of the chiral condensate in QCD
(Iop Publishing Ltd, 2012-01-01)
The time evolution of the matter produced in high energy heavy-ion collisions seems to be well described by relativistic viscous hydrodynamics. In addition to the hydrodynamic degrees of freedom related to energy-momentum ...

Emergence of very long time fluctuations and 1/f noise in ideal flows
(American Physical Society, 2011-06)
This paper shows the connection between three previously observed but seemingly unrelated phenomena in hydrodynamic (HD) and magnetohydrodynamic (MHD) turbulent flows, involving the emergence of fluctuations occurring on ...
The SELGIFS data challenge: generating synthetic observations of CALIFA galaxies from hydrodynamical simulations
(Wiley Blackwell Publishing, Inc, 2018-09)
In this work we present a set of synthetic observations that mimic the properties of the integral field spectroscopy (IFS) survey Calar Alto Legacy Integral-Field Area (CALIFA), generated using radiative transfer techniques ...
Long-term memory in experiments and numerical simulations of hydrodynamic and magnetohydrodynamic turbulence
(American Physical Society, 2014-05)
We analyze time series stemming from experiments and direct numerical simulations of hydrodynamic and magnetohydrodynamic turbulence. Simulations are done in periodic boxes, but with a volumetric forcing chosen to mimic ...
Evaluation of weakly compressible SPH variants using derived analytical solutions of Taylor-Couette flows
(Elsevier, 2013-09)
Smoothed particle hydrodynamics (SPH) is a relatively young meshless particle method used in fluid simulation. The method has not yet reached a mature state and still is in the need of rigorous evaluation tests that ...
Experimental Investigation of the Hydrodynamic Coefficients of a Remotely Operated Vehicle Using a Planar Motion Mechanism
(ASME-AMER SOC MECHANICAL ENGNEW YORK, 2012)
The determination of hydrodynamic coefficients of full scale underwater vehicles using system identification (SI) is an extremely powerful technique. The procedure is based on experimental runs and on the analysis of ...
