  • Accurate estimates of hull girder loads are crucial to an optimized design of sailing ships. However, while such calculations are considered satisfactory on mild waves, extreme behavior is still subject to approximations.

    The design practices usually involve long simulations from which the statistical distribution of the extreme events is identified. These simulations are generally done with potential linear solvers, which have some limitations. For this reason the design methodology consider large safety factors.

    Using CFD, one can get very accurate simulations, however the computational cost is heavy, and only a set of simulations over a short duration is practically possible.

    The PhD thesis will thus aim to study the balance precision/cost induced by the settings, the models, and the workflow, in order to improve the performance of CFD to simulate longer time series. If required a coupling with a structural solver will be considered.

    The work is carried out in the IIHNE team of the LHEEA within the framework of the Ecole Centrale – Bureau Veritas Chair, with numerous interactions with the Bureau Veritas research department. The CFD code co-developed in this Chaire framework is based on OpenFOAM.
