The implementation of advanced low-emission aircraft engine technologies and the
reduction of noise from airframe, fan, and jet exhaust have made noise contributions from an …

To investigate the effects of the nozzle-exit conditions on jet flow and sound fields, large-
eddy simulations of an isothermal Mach 0.9 jet issued from a convergent-straight nozzle are …

Experience gained from previous jet noise studies with the unstructured large-eddy
simulation flow solver “Charles” is summarized and put to practice for the predictions of …

This paper summarizes experimental studies of incompressible elliptic jets of different
aspect ratios and initial conditions, and effects of excitations at selected frequencies and …

We present experimental results for the acoustic field of jets with Mach numbers between
0.35 and 0.6. An azimuthal ring array of six microphones, whose polar angle,, was …

Round jets originating from a pipe nozzle are computed by large-eddy simulations (LES) to
investigate the effects of the nozzle-exit conditions on the flow and sound fields of initially …

Five isothermal round jets at Mach number and Reynolds number originating from a pipe
nozzle are computed by large-eddy simulations to investigate the effects of initial turbulence …

Large-eddy simulations (LESs) of isothermal round jets at a Mach number of 0.9 and a
diameter-based Reynolds number Re D of 10 5 originating from a pipe are performed using …

The use of particle image velocimetry (PIV) to study the spatial and temporal features of
unsteady fluid flow has increased dramatically in the past five to ten years. One particular …

Three isothermal round jets at a Mach number of 0.9 and a diameter-based Reynolds
number of 105 are computed by large-eddy simulation using four different meshes in order …
