基于GAMBIT的舰船全附体几何建模

Fully Appendage Modeling of Ships based on GAMBIT

几何体建模是进行CFD计算一项重要的基础工作.对于具有复杂附体结构的舰船,如何精确快速进行建模将决定其水动力CFD计算的精度和效率.基于优秀的CFD前处理软件GAMBIT强大的几何建模功能,实现对水面舰船包括螺旋桨、舵、减摇鳍、舭龙骨以及桨轴支架的全附体建模,为考察其在全附体情况下的水动力打下了良好基础,以期提高舰船CFD计算的仿真度和精度.

Geometry modeling is the fundamental work of Computational Fluid Dynamics.Because of the complicated structure of ship appendages, it is important to build the geometry quickly and accurately.GAMBIT, the excellent pre-processor of CFD was adopted in this paper to build the geometry modeling of fully appendages for surface ship.The geometry modeling of fully appendages such as propellers, rudders, stabilizing fins, bilge keels and V-brackets of which were built in order to improve the simulation and precision of Ship Computational Fluid Dynamics.
