An overview of the selected results of the European Union Project EFFORT

The European-Union EFFORT (European Full-Scale Flow Research and Technology) project focuses on validating and introducing innovative Computational Fluid Dynamics (CFD) prediction methods for the performance of the ship/propeller combination at the full scale, instead of the usual model scale. Within the project existing CFD codes have been extended, extensive full scale and model-scale (PIV) flow measurements have been conducted, and validation of the CFD predictions has been carried out. In this paper an overview of the EFFORT project results is given and the innovations that have been implemented by EFFORT consortium group are shown. The model scale PIV experiments that have been carried out on two vessels are also discussed. In the paper there are shown some of the validation results based on these experiments. Finally there are selected examples of the calculations that have been carried out by CTO S.A. in which the validated CFD computations have been used as a design tool replacing the model tests which are normally carried out.
