A database of flow and near pressure field signals obtained for subsonic and supersonic jets impinging on a flat or a perforated plate using large-eddy simulations

Résumé

The time signals obtained in the flow and near pressure fields of subsonic and supersonic jets impinging on a flat or perforated plate computed by highly-resolved compressible largeeddy simulations (LES) using cylindrical coordinates (r, θ, z) have been stored in a database. As is the case for the data obtained recently for free jets, they can be shared with other researchers, upon request by email, to investigate, for instance, the development of turbulent structures and noise generation mechanisms in impinging jets. The jet conditions (Mach and Reynolds numbers, temperature) and nozzle-exit boundary-layer characteristics (thickness, velocity profile, fluctuation level), the LES grid parameters and the recorded signals (nature and location of the variables stored, time duration and sampling frequency) are briefly described in this short note.
