Abstract
A ship’s nominal wake fraction is a key parameter in the design
of the marine propulsion system, i.e. the the marine propulsor
and main engine. Determination of the wake fraction is
commonly done through empirical formulas and / or based on
model-scale experiments. However, a discrepancy exists between
the model- and full-scale estimation results because of
the way scaling is applied. Speed trials are conducted to estimate
the full-scale nominal wake fraction. Results show the
ability of the developed speed-trial methodology to provide an
initial estimation of the full-scale nominal wake. However,
comparison between the empirical, model-scale, and full-scale
results fails to provide conclusive results. No real insight into
the validity of the estimated full-scale nominal wake fraction
could be established. However, the applied methodology is
deemed to have value but additional research is required before
further conclusions can be drawn.
