Experimental campaign investigates turbulence and velocity in subsonic nozzle jets, indicating validation potential for simulations.
Understanding the development of turbulent jets in subsonic nozzles is essential for improving jet noise prediction models and for validating high-fidelity numerical simulations in aerospace applications. Within the framework of the NATO STO AVT-415 activity, a dedicated experimental campaign was carried out at the Italian Aerospace Research Center (CIRA) to investigate the velocity field and turbulence characteristics at the inlet and exit of a novel subsonic nozzle configuration using hot-wire anemometry (HWA). The results offer a comprehensive description of the flow evolution downstream of the nozzle exit and a detailed characterization of the turbulence properties upstream of the nozzle. These measurements are of significant importance for validating numerical simulations and establishing accurate boundary conditions.
