Abstract : A new pressure-driven shock tube has been designed, incorporating a spring-loaded ball valve in lieu of a diaphragm. One rigid driver section is used to generate shock waves simultaneously in one or more flexible driven sections. Long flexible copper tubings have been used as a driven section with a square cross-section test section. Luminous shocks have been successfully produced in air, argon and xenon for tubings as small as 1.78 mm in inner diameter and well over 1000 in length-to-radius aspect ratio.
