基于滑移网格的潜艇旋臂试验数值模拟∗

摘要

The hydrodynamic coefficients are significant for the hydrodynamic performance of submarine. To obtain the rotary derivative of submarine with high precision, the structured mesh and sliding mesh with fixed coordinates are adopted. Simula⁃tions based on SUBOFF submarine are performed in two different turbulent models, and the simulation results are compared with the experimental data. The numerical simulation error shows to be under 8%, which is satisfied with the engineering re⁃quirement and verify the feasibility of this method.%潜艇水动力系数对潜艇操纵性研究具有重要意义。为了获取较高精度的潜艇旋转导数，以分区结构化网格为基础，采用基于固定坐标系的滑移网格方法，对SUBOFF潜艇进行旋臂试验数值仿真。并对比两种不同的湍流模型下仿真结果，误差均在8％以内，满足工程要求，验证了方法的可行性。
