Hybrid calculation method for reusing CFD information and metamodeling.
This paper demonstrates that the differences between model-scale flow and full-scale flow have significant impacts. It has been found that in various projects, the ranking of design candidates in optimization or the operating conditions in trim optimization differ between model-scale and full-scale calculations. The differences between model-scale and full-scale are particularly evident in the relatively different boundary layers and breaking waves behind the transom stern. Therefore, in simulation-based design projects, full-scale analysis is considered preferable. In rule-based optimization, the choice of approach becomes more complex due to time and computational resource constraints. The hybrid calculation method that reuses CFD information and metamodeling is seen as a technology that paves the way for using full-scale CFD as a standard option in optimization.
