[photograph 2012.201.b1205.0980]... Valentine's day, 1929, seven members of the notorius "Bugs" Moran gang, trapped by enemy gunmen, were lined up against a brick wall in a dingy Chicago garage and mercilessly bled to death by screeching bullets...
Broadband shock-associated noise in screeching and non-screeching underexpanded supersonic jets... Screech is removed by means of a notched nozzle, and the properties of the broadband shock-associated noise in the screech-free configuration are compared to that in a screeching flow...
3d density reconstruction of a screeching supersonic jet by synchronized multi-camera background oriented schlierenInternational audienceThis work describes the application of 3D Background Oriented Schlieren (3DBOS) to the experimental analysis of the mean and instantaneous 3D structures of supersonic under-expanded screeching jets...
Oscillation modes in screeching jetsIn this Note, the origin of the oscillation modes of screeching round jets is investigated by assuming that the feedback part of the aeroacoustic loop responsible for screech noise can be modeled by considering the neutral acoustic wave modes of the equivalent ideally expanded jets
