Influence of initial turbulence level on the flow and sound fields of a subsonic jet at a diameter-based Reynolds number of 10(5)

Effects of nozzle-exit boundary-layer profile on the initial shear- layer instability, flow field and noise of subsonic jets.7. Effects of nozzle-exit

The LES of round jets at M = 0.9 and Re D = 10 5 presented in this paper show the significant effects of the nozzle-exit boundary-layer thickness and turbulence conditions on

To extend and complete the previous studies reported above, the present work aims to carefully investigate the influence of the nozzle-exit boundary-layer thickness in initially

In contrast to the case of small-scale forcing, where mixing of potential vorticity occurs largely through the action of small-scale eddies, mixing of potential vorticity in this

Normalized turbulent energy dissipation rate C ε variation versus Taylor microscale Reynolds number Re λ for the measured locations in the VG wake compared to DNS 35–38

The shear flow at the surface tends to destabilize the surface fluctuations, and the critical strain rate y~, which is the minimum strain rate required for unstable fluctuations,

A Power Density Function (PDF) of inter distances between two consecutive vortices can be computed from the statistic of P.I.V. fields and is plotted on figure 12. The

The simulations with nozzle-interior turbulence modelling focused on adaptive isotropic mesh refinement of the internal boundary layer (prefix BL ), synthetic turbulence (suffix Turb
