Flow Characteristics of UT-Kashiwa Hypersonic Wind Tunnel
by
Osamu Imamura, Tadaharu Watanuki, Kojiro Suzuki, and Kashiwa Wind Tunnel Working Group (Univ. of Tokyo)
ABSTRACT
In this study, the flow characteristics of UT-Kashiwa hypersonic wind tunnel are obtained by measuring the Pitot pressure distribution.
In this wind tunnel, the Mach 7 and 9 hypersonic nozzles are inherited from its predecessor facility in UT-Komaba Campus. From a
viewpoint of the operation safety and cost, the maximum stagnation pressure at Kashiwa facility is 950 kPa, which is much lower than at
Komaba facility (5 MPa). To evaluate the uniformity of the freestream of this tunnel, the Pitot pressure traverse was conducted for the
Mach 7 nozzle by using the rake of 11 Pitot tubes with 20mm intervals in the radial direction. The measurement has been done at every 30
or 45 degrees in the circumferential direction and also at some streamwise locations. The Mach number calculated from the settling
chamber pressure and the test-section static pressure is nearly 7, which is almost the same as the Mach number obtained from the Pitot
pressure (about 14 kPa) on the center line. The Pitot traverse shows that the uniform flow core with 120 mm diameter is formed both at the
nozzle exit (200 mm in diameter) and at the center of the test section. Such ratio of the core diameter to the nozzle exit diameter seems
quite resonable, comparing to other existing hypersonic wind tunnels. The cross-sectional Mach number distribution shows slight deviation
from the axi-symmetric pattern because of the misalignment of the nozzle and the test section to the tunnel center line. Consequently, the
highly uniform Mach 7 flow is obtained in this facility, though the nozzle is used under the off-design operation pressure, that is, the offdesign Reynolds number.
