Selfsimilar structures in turbulent flows and the construction of LES closures (B07*)

• Subject Area: Mathematics
• Term: from 2018 to 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 235221301

The applied science goal of the project is to quantitatively characterise self-similar structures in turbulent flows and, if this can be achieved, utilise the resulting insights to construct novel Large Eddy Simulation (LES) closures. To this end, Direct Numerical Simulation (DNS) data of turbulent flows as well as observational data from atmospheric turbulence will be analysed using advanced multiscale data analysis techniques. At the level of methods developments, the project aims to generalise multiscale shearlet decompositions and combine them with other, complementary data analysis techniques.
