Hybrid large-eddy type simulations for chevron nozzle jet flows are performed at Mach 0.9 and Re = 1.03 × 10 6. Without using any subgrid scale model (SGS... X Hao,PG Tucker,S Eastwood - 《International Journal of Heat & Fluid Flow》 被引量: 122发表: 2009年 Computational and Experime...
direct numerical simulations (DNS) offer the highest degree of accuracy, as they start with no physical approximations about how a fluid will flow and recreates the process “from scratch” numerically down to the smallest levels of turbulent motion (“Kolmogorov-scale” resolution). Due ...
In order to fully understand the velocity distribution of jet flow of the main nozzle in an air-jet loom,which is used for optimizing the process parameters of weft insertion system,the numerical simulation based on weft insertion flow field of main nozzle is carried out by the computational fl...
The decay of a jet discharging from a circular nozzle parallel to and displaced from a solid surface is investigated under conditions where the transitional process from circular-jet flow to oblate wall-jet flow begins in the initial, transition or self-preserving regions of the original jet. The...
However, somewhere in the transition regime, the flame tip closes, and large-scale structures develop which wrinkle the flame. This is in contrast to the brush-type structure seen in the normal-gravity flames. The flame lifts off the nozzle tip, although the stand-off distance is almost half...

Turbulence injection over the whole height of the nozzle ducts accelerates the Reynolds-averaged Navier–Stokes to large-eddy simulation transition in both external and internal mixing layers, which is in better agreement with the experimental results. The transition length is further reduced when the ...
As a result, local crossflow velocity magnitudes increase significantly at each jet nozzle location, as illustrated by data provided within Fig. 8. For rib position 4, each V-rib is located downstream of an impingement jet at a smaller Z-location. Each rib in this arrangement is then exposed...
