内容記述 | After the upstream part of the JAXA blow-down 1 m x 1 m supersonic wind tunnel was modified to improve its flow qualities, the pressure fluctuations were measured in the test section at Mach numbers from 1.4 to 4.0. The rms values of the total (pitot) pressure fluctuations measured at the center of a cross section were reduced significantly, to about 1/2-1/6 of their former level. The ratio of the rms values of the static pressure fluctuations measured at the test section wall to dynamic pressure values decreased from about 0.5 percent to 0.1 percent with increasing tunnel Mach number. However, the level of the static pressure fluctuations at Mach 2.0 was one order of magnitude larger than that of a high-speed in-draft wind tunnel, which is reputed to be a quiet tunnel. | |||||
