Study of Mean- and Turbulent-Velocity Fields in a Large-Scale Turbine-Vane PassageSource: Journal of Engineering for Gas Turbines and Power:;1980:;volume( 102 ):;issue: 001::page 88Author:D. A. Bailey

Abstract: Laser-Doppler velocimetry was used to investigate the secondary flow in the endwall region of a large-scale turbine inlet-guide-vane passage. The mean and turbulent velocities were measured for three different test conditions. The different test conditions consisted of variations in the blade aspect ratio and the inlet boundary-layer thickness or all three cases, a passage vortex was identified and its development documented. The turbulent stresses within the vortex were found to be quite low in comparison with the turbulence in the inlet boundary layer.
