HySim - Development and implementation of high-fidelity hybrid simulation methods for ship propulsion

Short description

The global goal of this BMWi-funded project, which is a sub-project in the joint project "HyDesign" (Hybrid Simulation Methods in the design process of Energy Saving Devices and Propellers), is the development of the model based on the latest developments in turbulence modeling (Large  Eddy Simulation or LES) and the tool common for industry to evaluate measures to reduce vibration on propellers and energy saving Devices (ESD). The following scientific sub-objectives were formulated:

  • Improvement of hybrid turbulence modeling
  • Substantial reduction of computing times
  • Validation of a novel technology for the calculation of unsteady flows around ships with propellers and ESD
  • Development and validation of a common calculation tool for industrial purposes

Based on this, the following project goals for the subproject "HySim" can be derived in summary:

  • Reduction of computing time by decomposing computing areas and selecting optimal calculation strategies (30%)
  • Validation with the help of experimental model experiments
  • Reproduction of the real ship resistance components (improvement of the forecast with hybrid methods by 15%)
