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…

Lumley Decomposition of the Turbulent Round Jet Far-field. Part 1 -- Kinematics
Azur Hodžić, Knud Erik Meyer, Clara M. Velte +1
The current work presents a tensor formulation of the Lumley Decomposition (LD), introduced in its original form by Lumley (1967b), allowing decompositions of turbulent flow fields…

Lumley Decomposition of the Turbulent Round Jet Far-field. Part 2 -- Dynamics
Azur Hodžić, Knud Erik Meyer, William K. George +1
In the current work the reconstruction of the far-field region of the turbulent axi-symmetric jet is performed in order to investigate the modal turbulence kinetic energy productio…
