This study aims at quantifying the effects of off-design operation on the aerodynamic performance of a high deflection steam turbine blade linear cascade. The flow incidence on the leading edge of the blades was varied from -15.3° to +21.0° while comprehensive measurements of the resulting flow-fields upstream and downstream of the test section were conducted. This allowed calculating the profile loss coefficient which proved to be insensitive to flow incidence. The experimental results were found to be in good agreement with the output from an in-house numerical investigation using a commercial CFD package. Copyright © 2009 by ASME.
