Bureau veritas sloshing model tests & CFD calculations within ISOPE benchmark

The objective of this paper is to present the sloshing model tests and the corresponding CFD calculations carried out by Bureau Veritas (BV) within the framework of the second ISOPE sloshing benchmark. It has to be mentioned that the first ISOPE sloshing benchmark was proposed in order to establish best practices for sloshing model tests. Therefore the major actors (universities, research institutes and industrial partners) involved in sloshing model tests campaigns decided to join this project. Carrying out its own sloshing model tests since 2006, BV decided to contribute through its expertise to this benchmark. This paper is divided in three main sections. The first one aims at managing the inputs; the second one details the processing of the experimental data and the third one aims at giving some first comparisons between experimental results and numerical calculations (CFD and Wagner's model). This work follows the studies carried out by the different stakeholders of the 2012 ISOPE sloshing benchmark and points more in details, the key parameters driving the discrepancies that may occur in the results. It is thus foreseen to mainly focus on the accurate reproduction of the tanks motion by the test rig, on the tank alignment on the test platform and on the precise filling of the tank. It has been agreed that additional outputs have to be issued for this second benchmark. Firstly, impact high speed videos will help to identify the impact types (air pocket or direct). Secondly, specific BV features such as high accuracy six-degrees-of-freedom (d-o-f) measurement, global force and crest memory cards measurements are presented.
