 note = {The unsteady flow field of an axial-flow turbine rotor was investigated experimentally using a Laser Doppler Velocimetry (LDV) system. Detailed measurements of the time-averaged and time-resolved distributions of the velocity, flow angle, turbulence intensity, etc. were carried out at a low Reynolds number condition, Re(sub out, RT) = 3.5 x 10(exp 4). The data obtained were analyzed from the viewpoints of both an absolute (stationary) frame of reference and a relative (rotating) frame of reference. The effect of the turbine nozzle wake and secondary vortices on the rotor flow field was clearly captured. It was found that the nozzle wake and secondary vortices are suddenly distorted at the rotor inlet, because of the rotating potential field of the rotor. The nozzle flow (wake and secondary vortices) and the rotor surface flow (boundary layer flow) interact intensively inside the rotor passage. The periodic fluctuation of the relative velocity on the rotor suction surface due to the nozzle effect is as much as 20 percent of the mean rotor exit velocity., 資料番号: AA0063908018, レポート番号: JAXA-SP-07-026E},
