本研究在多重網格流域中，使用滑移網格模型研究了基於有限體積法下全附屬物的DARPA SUBOFF模型，並使用計算流體動力學方法（CFD）進行模擬。基於Boussinesq假設，將非穩態雷諾平均Navier-Stokes（URANS）方程與剪切應力傳遞（SST）k-ω紊流閉合耦合。為了模擬非穩態運動並捕獲非穩態間相互作用，採用了滑移網格模型來模擬多個運動區域中的流體流動。本研究利用基於壓力的求解器，即壓力耦合方程的半隱式算法（SIMPLEC），基於預測與校正方法以不可分離的方式用於不可壓縮流。並透過與已發布的實驗數據和其他數值結果進行比較，對數值模擬進行了驗證。

A Computational Fluid Dynamics (CFD)-based simulation using a finite volume code for a full-appendage DARPA SUBOFF model was investigated with a sliding mesh model in a multi-grid fluid domain. Unsteady Reynolds Averaged Navier-Stokes (URANS) equations were coupled with a Shear Stress Transport (SST) k-ω turbulence closure based on the Boussinesq hypothesis. In order to simulate unsteady motions and capture unsteady interactions, the sliding mesh model was employed to simulate flows in the fluid domain that contains multiple moving zones. The pressure-based solver, Semi-Implicit Method for Pressure Linked Equations-Consistent (SIMPLEC) algorithm, was employed for incompressible flows based on the predictor-corrector approach in a segregated manner. The numerical simulation was validated by comparison with the published experimental data and other numerical results.
