Abstract:

Volume V of this series contains computer print-outs displaying the results of harmonic analyses of selected test runs. The steady and 10-harmonic coefficients for wake flow angles and associated velocity components are shown. This material is compiled to enable understanding of the wake structure additional to that derived from the spectrographs in other volumes. Author
