Sound in the far-fieldby phase-microphones array
(field tests and large-anechoic wind tunnels)
Phenomenological research by Computational aero-acoustics (CAA)
- DNS, LES (direct approaches)
- DNS+LEE, LES+BEM, RANS+SNGR (hybrid approaches)
Surface pressure sensors and acoustic analogies
e.g. Pressure transducers and Curle analogy
Experimental noise-source identification by PIV
statistical techniques (spatio-temporal velocity correlations)
time-resolved analysis (velocity or derived pressure spectra)详细>
