Influence of physical-chemical properties of gases on interaction between shockwaves and convex cylindrical surfaces
Abstract
The interaction of shockwaves with cylindrical surfaces is investigated in a square shock tube with Mach numbers ranging from 1.5 to 6.0 and initial pressures from 10 to 30 mm Hg. Cylindrical segments with radii 123 mm were employed. Shadowgrams and interferomgrams of the interaction regions were registered in argon, nitrogen and carbon dioxide, which were used to model different depths of physical-chemical transformations in the gas behind the shockwave. The influence of physical and chemical processes on shockwave interaction is described. The changes occurring in the flow picture are similar to those observed on plane wedges.
