摘要:
This note describes a short series of experiments investigating the nature and magnitude of the differences in the noise field from subsonic cold air jets having circular and elliptic orifices. An anticipated increase in the noise level occurs in directions normal to the major axis, but other changes having more obscure origins are also revealed.
