OPEN_FPE_IFT

This package performs a standard analysis of given turbulent data and a new stochastic treatment of the turbulent cascade process.

This is a user-friendly open-source Matlab package developed by the research group Turbulence, Wind energy and Stochastics (TWiSt) at the Carl von Ossietzky University of Oldenburg (https://uol.de/en/physics/twist). This package enables to perform a standard analysis of given turbulent data and extracts the stochastic equations describing the scale-dependent cascade process in turbulent flows through Fokker-Planck equations. As the analysis of the scale-dependent cascade process through a hierarchy of spatial and temporal scales in turbulent flows is an integral part of turbulence theory, this interdisciplinary treatment of the turbulent cascade process has the potential for a new way to link the statistical description of turbulence (via common two-point increment statistics), non-equilibrium stochastic thermodynamics and local turbulent flow structures. The presented package can be used also for the analysis of other data with turbulent like complexity.
