Supersonic Interaction in the Corner of Intersecting Wedges at High Reynolds Numbers

摘要: As the distance from orifice in tip to wire is small and gas velocity of order speed sound a time response [isec might be expected, unless size hot electronics limit it longer time. A new probe with smaller diameter (0.0001 in.) less rapid area expansion (based on findings Sec. 6) was constructed placed end wall shock tube. The tube nitrogen, initially at atmospheric pressure. wave passing by produced an instantaneous change stagnation conditions sampled corresponding output photographed (Fig. 6), (time scale =100 jusec/cm, vertical = 0.05 v/cm). evidently about 200 //sec. experiment repeated using helium instead nitrogen and, as rise faster. It noted that much associated warming up glass. References 1 Blackshear, Perry L.
