摘要

本文介绍了全尺寸船舶试验计算流体动力学(CFD)仿真的验证和验证。根据三种不同功率设置的行业标准进行了速度/功率试验。根据环境影响对测量数据进行了校正，以获得理想的试运行结果。对船舶尺度非定常RANS进行了CFD模拟。对每个功率设置的网格细化灵敏度进行了评估。此外，还评估了所选网格的时间步长灵敏度。最后对对称条件和湍流模型的假设进行了验证。模拟结果与试验数据吻合良好，从而说明了数值方法在全尺寸下确定船舶性能的能力。

VERIFICATION AND VALIDATION OF CFD SIMULATIONS WITH FULL-SCALE SHIP SPEED/POWER TRIAL DATA

Verification and validation of Computational Fluid Dynamics (CFD) simulations of a full-scale ship trial are presented in this study. Speed/power trials were carried out according to industry standards for three different power settings. Measured data was corrected for environmental effects to obtain ideal trial runs. Ship-scale unsteady RANS CFD simulations were conducted. Grid refinement sensitivity was evaluated for each power setting. Furthermore, time-step sensitivity was assessed for the selected grids. Finally, assumptions regarding symmetry condition and turbulence model were verified. Simulated results were in good agreement with the test data, thus illustrating the capabilities of numerical methods to determine ship performance at full scale.
