Kolmogorov law 3d.

We want to test the prediction :

\[\boldsymbol{\nabla} \cdot \left( {\mathbf J_K} + {\mathbf J_P} \right) = -4 \left( \varepsilon_K + \varepsilon_A \right),\]

where

\[\begin{split}{\mathbf J_K}({\mathbf r}) \equiv \left\langle | \delta {\mathbf v} |^2 \delta {\mathbf v} \right\rangle_{\mathbf x}, \\ {\mathbf J_P}({\mathbf r}) \equiv \frac{1}{N^2} \left\langle | \delta b |^2 \delta {\mathbf v} \right\rangle_{\mathbf x}.\end{split}\]

This output computes and saves the components of the vectors \({\mathbf J}_\alpha\) averaged over the azimuthal angle (i.e. as a function of \(r_h\) and \(r_v\)), as well as radially averaged (as a function of \(r\)).
