摘要：

An uncertainty analysis is performed with the open source CFD toolkit, OpenFOAM, for four different ship models, KCS, DTC, KVLCC2, and JBC. A brief review of the practices in uncertainty analysis in the field of ship CFD is presented. Uncertainty analysis is performed for their resistance, sinkage and trim results using the two most popular uncertainty analysis methods. The study revealed that the two methods differ significantly from each other in total uncertainty prediction, and confirms that both validation and verification studies are case specific.
