摘要：

The deflecting oscillation of planar opposed jets was numerically simulated by large-eddy simulation (LES) at 35≤Re≤145000 and 4≤L/h≤40 (where L was the nozzles separation, and h was the height of the slit of the planar nozzle). The numerical results were validated by comparing with experimental results of planar opposed jets. The influencing factors of the deflecting oscillation of turbulent planar opposed jets, such as different work fluids, confinement of boundary and height-to-width ratio of nozzle exit, were investigated, and a map of the parameter space describing the deflecting oscillation of planar opposed jets was plotted. The results showed that various fluids had no significant influence on the periods of the deflecting oscillation, and the dimensionless periods of the deflecting oscillation increased with increasing confinement of boundary, but decreased with increasing height-to-width ratio of nozzle exit. © All Rights Reserved.
