Abstract: The influence of the internal degrees of freedom of various gases on density distribution and gas front motion in impulse supersonic jets is investigated. The gas jets were visualized by shadow and interference methods. The density distribution in the jet was obtained by means of electron beam absorption. Emission and absorption measurements were made at various wavelengths, including infrared, for the impulse nitrogen and carbon dioxide jets. Then the information about the conditions of the vibrational degre…
