Flow Field of a Dual-Stream Jet with External Wedge-Shaped Deflector
نویسندگان
چکیده
The research effort is a Reynolds-Averaged Navier-Stokes (RANS) investigation that looks at the flow-field and performance of a bypass ratio 8 nozzle with an external wedgeshaped noise suppressor, simulating the exhaust of a turbofan engine at takeoff conditions. Peak turbulence was reduced by the wedge on the side opposite the deflector, and it was increased in the initial region of the jet behind the deflector. Flow-field trends agreed with the expectations based on static jet experiments. The calculated thrust loss was 1.1% at takeoff conditions.

Effect of Wedge-Shaped Deflectors on Flow Fields of Dual-Stream Jets
The effect of wedge-shaped fan flow deflectors on the mean and turbulent flow-fields of dual-stream jets is investigated. Several wedge-shaped deflector concepts were used to create asymmetry in the plume of a dual-stream jet issuing from a scaled down version of the NASA Glenn ‘5BB’ bypass-ratio 8 turbofan nozzle. The deflector configurations comprised internal and external wedges with and wit...

We present a methodology for the computation of flow fields involving complex perforated surfaces in propulsion applications. Of particular interest is the treatment of perforated flaps used as wedge-shaped fan flow deflectors for reducing jet noise of a supersonic turbofan engine. A three-dimensional Reynolds-Averaged Navier-Stokes solver is used to compute the flow field of the external jet p...

This article presents experimental and computational analyses of the flow field associated with porous wedge-shaped deflectors used for jet noise reduction in turbofan engines. The goal is to characterize the key parameters affecting the flow field in order to construct a macroscopic computational model of the deflector that obviates resolution of its detailed perforations. The model simulates ...
متن کاملJet Noise Suppression with Fan Flow Deflectors in Realistic-shaped Nozzle
This is an exploratory study of jet noise reduction using fan flow deflectors in a nozzle shaped like the exhaust of a separate-flow turbofan engine with bypass ratio 4.8. The deflectors directed the bypass plume downward and/or sideward relative to the core plume. Vaneand wedge-type deflectors were tested. The noise reduction achieved by the vane deflector was strong in the downward direction ...
متن کاملMean Flow – Acoustic Correlations for Dual-Stream Asymmetric Jets
We present an experimental study, comprising acoustic and mean-flow measurements, of several fan-flow deflector configurations in a subscale dual-stream supersonic turbofan nozzle. The deflectors encompassed internal vanes and external wedges. The aim of the study was to investigate trends of high-frequency noise reduction, in the direction of peak emission, versus the distortion of the velocit...
