Abstract Nowadays, remotely operated vehicle (ROV) is an integral part of the marine industry. In this study, the hydrodynamic performance of a specific model of ROV is evaluated by numerical and experimental simulations in different Reynolds numbers ranging from 39291 to 157163 and various angles of attack from 0° to 45°. Moreover, two rectangular cubic models with fillet and sharp edges are modeled for comparative study. The wind tunnel and the finite volume methods are used for experimental and numerical simulations, respectively, and the Menter's SST k-ω model is employed to simulate the turbulent flow. The leading edge geometry, angle of attack, and Reynolds number are found to be the most effective factors on the drag forces. Additionally, the fillet edge model had better hydrodynamic performance than the ROV and the sharp edge rectangular cubic model considerably.

遥控车水动力性能试验与数值研究

摘要 如今，遥控车（ROV）是海洋工业不可或缺的一部分。在这项研究中，特定模型的 ROV 的水动力性能是通过数值和实验模拟在从 39291 到 157163 的不同雷诺数和从 0° 到 45° 的各种攻角下进行评估的。此外，还对两个带有圆角和锐边的矩形立方体模型进行建模以进行比较研究。分别采用风洞法和有限体积法进行实验和数值模拟，采用 Menter 的 SST k-ω 模型模拟湍流。发现前缘几何形状、攻角和雷诺数是影响阻力的最有效因素。此外，
