Measurements were made at 8 axial locations to reveal the structure of the flow as it evolved through the cascade. Measurements were also made to reveal the effects of grid generated turbulence on this flow. The data set is unique in that not only does it give a comparison of elevated free stream turbulence effects, but also documents the developing flow through the blade row of a compressor cascade with tip leakage. 

Given on this page are the data files that were used in the above study.  The data is available in the following files.

Readme.txt : A description of the data presented in the three files below

veldata.zip (470KB) : The mean and turbulent velocity field data

specdata.zip (95MB) : The spectral results.  Note : this is a very large zip file.  Unzipped, the data is approx. 230 MB.

blade_loading.txt : The measured blade loading.
