Dynamic Mesh 기법을 통한 X-형 제어판 배치 잠수함의 가상구속모형시험

다국어 초록 (Multilingual Abstract)

X-form configuration of a submarine has advantages of better manoeuvrability than the cruciform configuration, which has been traditionally used. The X-form configuration has a much longer span of control planes than those of the cruciform configuration, so it has the advantage of generating larger control force. Its control system, however, is complex, because horizontal and vertical forces induced by control planes were coupled. For the reason above, its dynamic characteristics should be analysed by identifying a dynamic modelling and deriving hydrodynamic derivatives. The present study carried out for a submarine with an X-form configuration. The test model was BB2, of which design was open most recently by Maritime Research Institute Netherlands. The hydrodynamic force on the BB2 model was estimated using virtual Planar Motion Mechanism test using Computational Fluid Dynamics(CFD). To to this, SNUFOAM, an object-oriented open source CFD tool-kit, was used as a solver for Unsteady Reynolds-Averaged Navier-Stokes simulation. Standard k-ε was selected for turbulence model and dynamic mesh methods was used for dynamic PMM tests.
