Kolmogorov's inertial subrange is one of the most important classical theories in the fluid mechanics and provides the basis for our understanding of the energy balance in many turbulent flows found in the natural world.
We've developed a standardized, automatic algorithm that can be used to locate the most plausible bandwidth of Kolmogorov's subrange from the three-dimensional velocity within a given turbulent flow, observed or simulated. The algorithm is open source and is currently maintained at a GitHub repository: https://github.com/dortizsu/ARIIS.
Please use this algorithm and submit any bug reports to me, you can find my contact on the GitHub site or on my webpage. If you find this algorithm useful for your own work, please cite the repository and
