Uncertainty quantification for a sailing yacht hull, using multi-fidelity kriging

摘要

Uncertainty quantification (UQ) for CFD-based ship design can require a large number of simulations, resulting in significant overall computational cost. Presently, we use an existing method, multi-fidelity Kriging, to reduce the number of simulations required for the UQ analysis of the performance of a sailing yacht hull, considering uncertainties in the tank blockage, mass and centre of gravity. We compare the UQ results with experimental values. (C) 2015 Elsevier Ltd. All rights reserved.
