EFFECT OF AFTERBODY FORMS AND AFTERBODY FINS ON THE WAKE DISTRIBTUTION OF SINGLE-SCREW SHIPS

The wake distribution is an important parameter regarding propeller-induced vibrations. The present report is a description of the influence of afterbody form, particularly section shape, upon wake distribution. Examples are also presented showing how after body fins can be applied to improve unfavourable wake distribtuions.
