The choice of turbulence model can have a strong impact on results for many
turbomachinery zones. Palliative corrections to them and also transition modeling can have …

The results of a series of large-eddy simulations of heated and unheated jets using
approximately 10 6 grid points are presented. The computations were performed on jets at …

Data for subsonic, hot and cold axisymmetric jets are reviewed, with emphasis on the high
subsonic Mach numbers that are of interest for jet noise applications. Data for the self-similar …

CURRENTLY, nonintrusive temperature-measurement techni-ques available for use in
turbulent-flow studies in which the local pressure is unknown are limited to sampling rates of …

Real challenges to suppress undesirable fluid-excited acoustics are posed by a wide variety
of engineering disciplines. Noise regulations, passenger comfort and component stability …

An analysis of the sound radiated by three turbulent, high-speed jets is conducted using
Lighthill's acoustic analogy (Proc. R. Soc. Lond. A, vol. 211, 1952, p. 564). Computed by …

Low-frequency noise sources in heated single-stream jets were identified by cross-
correlating turbulent density fluctuations ρ′ with the far-field sound pressure fluctuations …

The characteristic length and time scales of turbulence are reported in some detail for jet
flows. The objective of the work is to determine the frequency dependence of these two-point …

Prediction of flow-field properties in supersonic jets using computational fluid dynamics
(CFD) code predictions has become routine; however, obtaining accurate solutions …

A molecular Rayleigh scattering technique is utilized to measure gas temperature, velocity,
and density in unseeded gas flows at sampling rates up to 10 kHz, providing fluctuation …
