PARAMETRIC INVESTIGATION OF EESC-USP AEROACOUSTIC FAN RIG
R.G. Cuenca, UFSC, Brazil; P. Celso Jr.¹, B.M. Rocamora¹; ¹EESC-USP, Brazil
An aeroacoustics parametric campaign was conducted at the EESC-USP low speed Fan Rig changing shaft speed, rotor-stator spacing and throttling. A new curve was fitted on fan spectra and the use of Kriging regression makes the understanding of fan noise behavior easier and the expected error shows that the regression mimicates the real surface quite well.
