Superpipe Data
The mean velocity profiles obtained in the Superpipe facility are now available. Please click on the links given below to obtain the data files for each Reynolds number. The files are text files. The Reynolds number is based on pipe diameter and average velocity. There are 26 profiles altogether. The data have not been corrected for Pitot tube displacement effects, nor for any other effects. The facility is described here . For a more complete description of the facility, data acquisition and analysis procedures, including recommendations on corrections for Pitot tube displacement effects, see:
Mark V. Zagarola , “Mean Flow Scaling of Turbulent Pipe Flow,” Ph.D. Thesis, Department of Mechanical and Aerospace Engineering, Princeton University, June 1996.
A brief description of the recommended Pitot probe velocity gradient corrections are contained in the file probecor.pdf , which can be read using Acrobat Reader.
NOTE: Further studies at Princeton have revealed that the error in measured static pressure has a more significant effect on the mean velocity analysis than previously recognized. A new study of this error is given in B.J. McKeon and A.J. Smits ‘ Static pressure correction in high Reynolds number fully developed turbulent pipe flow ‘ (2002) Meas. Sci. Tech. 13, 1608-1614.
