This article reviews techniques applicable to enhancing the mixing of jets, with particular
emphasis on infrared (IR) signature reduction of high-speed jets. Following a brief …

The interaction of solid particles with the temporal features of a turbulent flow has direct
relevance to problems in particle and spray combustion and the processing of particulate …

An experimental study involving flow visualization and two-component LDV measurements
has been undertaken to elucidate the deformation of an axisymmetric jet (ReD≈ 1950 and …

An experimental investigation was undertaken to study mixing processes in a coaxial jet,
where the inner jet geometry is a lobed mixer. Various inner jet nozzle geometries were …

Several years ago, GE Aircraft Engines realized that with the expected increased stringency
of Stage 4 noise regulations, the continued thrust growth of engine families, and increasing …

Evaporative sprays are encountered in a wide range of engineering applications. Since
clustering of droplets in sprays leads to strong inhomogeneity in the spatial distribution of …

A study of noise bene t, vis-a-vis thrust penalty, and its correlation to turbulence intensities is
conducted for freejets issuing from lobed nozzles. Four convergent nozzles with constant …

This report describes the work performed by General Electric Aircraft Engines (GEAE) and
Allison Engine Company (AEC) on NASA Contract NAS3-27720 AoI 14.3. The objective of …

An aspect ratio 3 rectangular nozzle with design Mach number 2 was used to investigate the
effects of trailing edge modifications on mixing enhancement and to explore the sources of …

The mixing promoting capability of right-angled triangular tab with sharp and truncated
vertex has been investigated by placing two identical tabs at the exit of a Mach 2 axi …
