Dissipation-based proper orthogonal decomposition of turbulent Rayleigh-Bénard convection flow
Peder Jørgensgaard Olesen, Laurent Soucasse, Bérengère Podvin +1
We present a formulation of proper orthogonal decomposition (POD) producing a velocity-temperature basis optimized with respect to an dissipation norm. This decomposition is…
Combined proper orthogonal decompositions of orthogonal subspaces
Peder J. Olesen, Azur Hodžić, Clara M. Velte
We present a method for combining proper orthogonal decomposition (POD) bases optimized with respect to different norms into a single complete basis. We produce a basis combining d…
Spectral response between particle and fluid kinetic energy in decaying homogeneous isotropic turbulence
Martin Schiødt, Azur Hodzic, Fabien Evrard +3
In particle-laden turbulence, the Fourier Lagrangian spectrum of each phase is regularly computed, and analytically derived response functions relate the Lagrangian spectrum of the…
Phase proper orthogonal decomposition of non-stationary turbulent flow
Yisheng Zhang, Azur Hodzic, Fabien Evrard +2
A phase proper orthogonal decomposition (Phase POD) method is demonstrated, utilizing phase averaging for the decomposition of spatio-temporal behaviour of statistically non-statio…
Triad interactions investigated by dual vortex shedding
Preben Buchhave, Mengjia Ren, Clara Marika Velte
The study of the exchange of momentum and energy between wave components of the turbulent velocity field, the so-called triad interactions, offers a unique way of visualizing and d…
