Jeroen Wackers, Ecole Centrale de Nantes: Adaptive grid refinement for ship flow calculation
The computation of the water flow around ships is very challenging. On one side, this is caused by the need to model the water surface and its interaction with the ship hull. Also, the high Reynolds numbers of these flows require fine grids and thus high computational power. ISIS-CFD, the ship flow code developed at Ecole Centrale de Nantes, has evolved over the years from an academic research code to a mature method that is able to compute realistic flow scenarios for industrial applications. In the first part of my talk, I will present ISIS-CFD and its ability to compute steady wave patterns, unsteady ship-wave interaction, and ship motion.
In the second part, I present my own work: the inclusion of automatic adaptive grid refinement in ISIS-CFD. Necessarily, the method is parallelised and based on unstructured grids. Test cases show its great potential for improving the accuracy of flow calculations.
