Interaction of 2-d wake and jet plume
NettetTwo-dimensional steady e owe elds generated by transverse injection into a supersonic e ow are numerically sim- ulated by integrating the Favre-averaged Navier -Stokes equations. Fine-scale turbulence effects are modeled with compressible K-≤ and second-order Reynolds-stress turbulence models. These numerical results are compared to … NettetBoth potential and wake interactions are usually the primary mechanisms related to the unsteadiness in turbomachines. ... 1994) visualized the pronounced jet-wake velocity pattern at the impeller outlet via different measurement techniques, such as laser Doppler velocimetry and hot-wire anemometer.

NettetMotivation for Hot Plume Interaction Testing The resulting potential from an enhancement of the similarity of the exhaust jet’s stagnation conditions and gas properties is pictured in Fig.1. It is defined as the maximum nozzle exit velocity as a ratio between the experimental and flight val-ues u max,exp/u max,flight. NettetRecent efforts at the National Center for Physical Acoustics at the University of Mississippi have refurbished two models for studying jet-plume/afterbody-wake interactions in the NCPA's 1-foot Tri-Sonic Wind Tunnel Facility. Both models have a 2.5 inch outer diameter with a nominally 0.5 inch diameter centered exhaust nozzle.
