Abstract

Synthetic turbulence generation (STG), a process of imposing pseudo-random fluctuations as an input to a high-fidelity so as to recover specified mean turbulent statistics, has been implemented in the NASA OVERFLOW 2.3d computational fluid dynamics solver. The applicability of STG to highly compressible flows is investigated by applying the method to a zero pressure gradient flat plate. Preliminary results obtained for Mach 5 and adiabatic wall conditions show the ability to generate turbulence on a computational inflow plane, recovering appropriate mean velocity profiles and Reynolds stresses in shorter distances than body-force tripping and with greatly reduced computational expense compared to digital filtering.
