Risultati finali

Report on noise impact from active technologies (fluidic actuators/air curtain) numerical simulations validated through dedicated experiments

The deliverable will describe the noise reduction achieved with the use of passive noise reductions technologies by describing the impact of the use of the different NRTs on small and full scale model and compare this to the baseline configuration. Focus will be made on optimization of the porosity behaviour with different parameter.
