Extracting the Spectrum by Spatial Filtering
Mahmoud Sadek, Hussein Aluie
We show that the spectrum of a flow field can be extracted within a local region by straightforward filtering in physical space. We find that for a flow with a certain level of reg…

Convolutions on the Sphere: Commutation with Differential Operators
Hussein Aluie
We generalize the definition of convolution of vectors and tensors on the 2-sphere, and prove that it commutes with differential operators. Moreover, vectors and tensors that are n…

Inviscid Criterion for Decomposing Scales
Dongxiao Zhao, Hussein Aluie
The proper scale decomposition in flows with significant density variations is not as straightforward as in incompressible flows, with many possible ways to define a `length-scale.…
