• Airfoil Flow Visualization and Pressure Measurements in High-Reynolds-Number Transonic Flow
  作者：Herbert Olivier、Thomas Reichel、Mitja Zechner

  DOI：10.2514/2.2098

  日期：2003.8

  Today most wind tunnels operated for aerodynamic testing are not able to reproduce flight Reynolds numbers. To overcome this problem, a shock tube flow is used to generate a high-Reynolds-number transonic flow. With this technique, Reynolds numbers up to 40 x 106 based on model chord length are attainable in the Mach number range between 0.6 and 0.9. Time-resolved surface pressure measurements, as well as flow visualizations, are performed for the airfoil BAC3-il/RES/30/21. Two models of different chord lengths, 80 and 100 min, have been used. The maximum Reynolds number achieved to date is 38 x 10(6) for a freestream Mach number of 0.8. The results show that by calibrating the test-section flow carefully, this wind-tunnel technique can generate high-Reynolds-number flows, allowing aerodynamic testing at low cost. The technique avoids the complex cryogenic wind tunnel and model technique, at the expense of relatively short running times and relatively small test-section cross size. The testing time is on the order of 10-15 ms, which is sufficiently long for flow establishment and development of a useful measuring phase with stationary or at least quasi-stationary flow.

  Dialkyl sulphites are formed selectively from alcohols in the halogen–pyridine–sulphur dioxide system. The behaviour of alkyl chlorosulphates in the pyridine–sulphur dioxide system has been investigated and the role of halogenosulphinate ion in this reaction is discussed.
