Abstract

Direct numerical and large eddy simulation of inhomogeneous flows are very sensitive to turbulent inflow boundary conditions. This contribution presents a new turbulent inflow data generation method based on an auxiliary simulation of forced turbulence. It combines the flexibility of synthetic turbulence generation methods with the accuracy of precursor simulations. The approach allows full control over turbulence properties and provides divergence-free boundary fields, featuring realistic Navier-Stokes dynamics.
