- Abstract
- The Stability in Waves committee of the 27th ITTC has investigated the significance of scale effects in air pressure on flooding model tests under atmospheric conditions. For this purpose, the committee classified the flooding cases into the trapped air case and vented air case and investigated the flooding process for a simple geometry, using the state equation of air and orifice equation. As a result, the committee concluded that the scale effect is large for the case of trapped air and small vent area. For the other cases, the effect is small and can therefore be neglected in the model test of a damaged ship. In addition, the committee proposed some directions that can be used to reduce the scale effect of air pressure. ？ 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
