DETERMINATION OF DIAPHRAGM OPENING-TIMES AND USE OF DIAPHRAGM PARTICLE TRAPS IN A HYPERSONIC SHOCK TUBE

摘要

Experimental investigations have been carried out in the UTICA’S 4 in. x 7 in hypersonic shock tube to measure diaphragm openingtimes and to evaluate shock tube performance with particle traps located near the diaphragm station. Calculations, based on simple theoretical models, have been made in order to obtain approximate comparisons with the experimental results.
