Effects of Unsteady Wakes on Flow Through High Pressure Turbine Passages With and Without Tip Gaps

  title={Effects of Unsteady Wakes on Flow Through High Pressure Turbine Passages With and Without Tip Gaps},
  author={R. Volino and C. D. Galvin and C. Brownell},
Experiments were conducted in a linear high pressure turbine cascade with wakes generated by moving upstream rods. The cascade included an adjustable top endwall that could be raised and lowered above the airfoils to change the tip gap. Conditions were considered with no tip gap, and gaps of 1.5% and 3.8% of axial chord. For each of these, cases were documented both with and without upstream wakes. The pressure distributions on the airfoils were acquired at the midspan and near the tip for each… Expand
