通过CATIA建立空投气垫船的三维模型,利用STAR-CCM+计算流体软件对空投气垫船的流场进行数值模拟,采用重叠网格策略对虚拟拖曳池流场进行网格划分,且由于空投气垫船在航行过程中涉及到空气和水介质,因此在模拟中选择多相流和VOF模型用来模拟自由界面。计算该模型在静水中不同航速下的兴波、水气两相分布情况及总阻力等水动力性能的变化规律,验证了STAR-CCM+平台对空投气垫船静水航行状态以及总阻力数值模拟的可靠性和有效性。
The 3D model of air drop hovercraft was established by CATIA, the flow field of it was simulated by STAR-CCM+ calculation fluid software, and overlapping grid strategy. Since the air drop hovercraft involved air and water medium during navigation, multiphase flow and VOF models were selected to simulate the free interface.The changes of the hydrodynamic performance of the wave and gas and the total resistance, we verify the reliability and effectiveness of the STAR-CCM+ platform on the hydrostatic navigation state of the hovercraft and the numerical simulation of total resistance.
