摘要：
This paper focuses on the visualization of both experimental and numerical results and presents research in a highly-loaded cold-flow transonic turbine under continuous and engine-representative conditions. Special focus was placed on blade row interaction at app. 10600 rpm. While the first step was the investigation of a single stage machine (stator-rotor), the second step extended the test rig to a one-and-a-half stage configuration (stator-rotor-stator). Measurements were carried out in the transonic test turbine at Graz University of Technology using Particle-Image-Velocimetry and Laser-Doppler-Anemometry. The main results of these experiments are discussed and compared to numerical simulations.
