Abstract
In this paper the results are discussed of wake measurements behind seven Victory models on scales varying from 50 to 18 and behind the Victory model boat D.C. Endert Jr. on scale 6.
The scale effect in the circumferential inequality of the wake distribution is examined.
The mean wake fractions of the models and the frictional wake fractions for a propeller placed behind a flat plate show a close analogy to the skin friction extrapolation diagram when plotted on a Reynolds number base.
