A linear turbine cascade with the VKI-1 profile was investigated in the cascade wind tunnels EGG at the DLR in Goettingen, Germany, and SB 301 at the Gas Turbine Establishment in Jiangyou, China. Data were obtained from wake traverse measurements downstream of the cascade using pneumatic probes and from blade surface pressure measurements. Additionally total pressure distributions and side wall boundary layers in the upstream flow field were measured with a pitot probe. The influence of side wall boundary layers, especially the displacement effects on the two dimensional flow field of a turbine cascade will be shown and a correction for these effects will be given. The results from EGG and SB 301 will also be compared with those from other European cascade wind tunnels.
