During rocket launching, the engine exhaust impinges on the launch structures, such as the
launch platform and the jet deflector, leading to a complex flowfield and generating strong …

The primary objective of this investigation is to determine experimentally the sources of jet
mixing noise. In the present study, four different approaches are used. It is reasonable to …

A systematic study has been undertaken to quantify the effect of jet temperature on the noise
radiated by subsonic jets. Nozzles of different diameters were tested to uncover the effects of …

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 …

In this paper, the origin and the properties of the oscillation modes in screeching non-ideally
expanded rectangular jets are investigated using compressible implicit LES of rectangular …

Extensive experimental evidence is now available to support the observation that there are
two components of jet mixing noise. They are the fine-scale turbulence noise and the noise …

Noise generation is investigated in subsonic isothermal round jets at Mach numbers M= 0.6
and M= 0.9, with Reynolds numbers ReD= 1700 and ReD≥ 105, using causality methods …

This investigation presents a unique and elaborate set of experiments relating the
generation of noise to the evolution of large-scale turbulence structures within an ideally …

The theory, design, and use of a focusing laser differential interferometer (FLDI) instrument
are described. The FLDI is a relatively simple, nonimaging, common-path polarization …

To locate noise sources in high-speed jets, the far-field sound pressure fluctuations
microphone showed weaker values. By moving the laser probe to various locations in the …
