摘要

这篇文章与作者之前对遥控水下机器人（ROV）运动的研究直接相关，其中ROV运动的数学模型是针对层流推导的。ROV运动的这种解决方案已经通过使用三维计算流体动力学（CFD）模拟进行了改进，该模拟允许模拟主要由螺旋桨产生的湍流。两种方法相结合，以获得更准确的流体动力学阻尼系数值，从而改进ROV运动速度的确定。讨论了求解结果，并与实验结果进行了比较。

A Motion Model of a Remotely Operated Underwater Vehicle: CFD Simulation

The article is directly related to the authors’ previous study of the remotely operated underwater vehicle’s (ROV) motion, where the mathematical model of the ROV motion is derived for laminar flow of water. This solution of the ROV motion has been improved by using the three-dimensional computational fluid dynamics (CFD) simulation that allows simulating the turbulent flow, which is mainly generated by propellers. Both methods were coupled to obtain more accurate values of hydrodynamic damping coefficients for the improved determination of the ROV motion velocity. Results of the solution are discussed and some of them are compared with the experiment.
