In a Ludwieg tube, the opening time of a quick-opening value which separates the high pressure section from the low pressure section is considerably longer than that of the diaphragm. In cases where the valve is located downstream of the test section, the disturbances generated by the opening of the value do not arrive at the test section after the flow at the exit of the test section becomes supersonic. On the other hand, in cases where the valve is located upstream of the test section, all of the disturbances at the valve propagate through the test section. In the present paper, the effects of the opening valve upstream of the test section wee clarified by the results of the pressure measurements for the different valves of the distance between the valve and the throat of the nozzle, the throat area of the nozzle and the plenum flow rate.
