DISTURBANCE OF A BOW SHOCK WAVE AND OF FLOW BEHIND IT IN THE CASE OF FLOW PAST BLUNT BODIES IN POLYATOMIC GASES

A review has been presented of the results of experimental investigations, on a ballistic unit of the Physical-Technical Institute, into the distortion of a bow shock wave and of fl ow behind the body in CCl2F2 and CF4 polyatomic gases.
The latest experimental works at the Physical-Technical Institute and abroad have also been reviewed. The distortion of the bow shock wave under the same conditions is identically manifested in the case of fl ow past a segmental body
and past a sphere alike, although for the sphere, fl ow separation occurs farther downstream of the bow shock. In the case of fl ow past a cylinder the initial distribution of the fl ow is observed in the compression zone behind the bow
shock wave.
