The measurement was performed in the impulsive facility HIEST. To change the Reynold's number, stagnation enthalpy was varied from H(sub 0) = 3.5 MJ/kg (Re = 6.0 x 10(exp 6)/m) to H(sub 0) = 8.2 MJ/kg (Re = 1.6 x 10(exp 6)/m). On the cone model, Eighty-six miniature co-axial thermocouples were flush - mounted on the surface of the model to measure heat flux distribution. Surface pressure fluctuation was measured in order to observe the second-mode instability in the boundary layer. The heat flux distribution measurement indicated that transition occurred on the model at approximately Re = 4.0 x 10(exp 6). Surface pressures exhibited peaks in their frequency spectra that were thought to represent second-mode instability., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672019, レポート番号: JAXA-SP-09-011}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {極超音速境界層における表面圧力変動の計測}, volume = {JAXA-SP-09-011}, year = {2010} }
