Abstract
Three-dimensional (3-D) power prediction method from model test has been widely accepted and used for many years. Form factor k is the most important characteristics of 3-D method and very crucial to the accurate power prediction. However, it’s rather difficult to get the accurate value of k for those ships with pronounced bulbous or large transom from model test. In this paper, a new method to predict power is proposed, using k from CFD while other data from model test (or experimental fluid dynamics (EFD)). Delivered power prediction using the combination of CFD/EFD method agrees well with sea-trial results.
