Velocity Measurements of Incident and Reflected Shock Waves in Various Gases and in Saturated Water Vapour,
FACHHOCHSCHULE WEDEL (GERMANY F R)
Pagination or Media Count:
Velocity measurements of incident and reflected shock waves have been performed by a four-beam-laserinterferometer. The beam distance for run-time determination was only 3.3 mm, thus insuring an instantaneous velocity measurement obtaind by shock-shock reflection ideal and by end wall reflection real.
