摘要

This volume contains an analysis of the data and compares the steady and unsteady results of this experiment with both analytical predictions and experimental data from previous work. The bulk of the data analysis was made for results taken at the blade midspan. There were two major findings. It was found that the unsteady oscillatory pressures were in excellent agreement with the unsteady potential flow theory of Verdon and Caspar for all conditions in which the flow was essentially two-dimensional. Also, the measured steady pressures were in good agreement with the steady potential flow predictions (and with previous steady experimental data) when the measured exit angle was the imposed down stream boundary condition for the analysis. This volume also offers some hypotheses to explain some of the details observed in the pressure and skin friction gage time histories and relates some previously published flow visualization results to these observations.
