“…Regions of the propeller are separately divided and intensive grids are used. To obtain better simulation results, a dense grid is also used in the closed area of the ROV [30]. The region where the ROV is located is also used with a denser grid for better simulation.…”

In recent years, Remotely Operated Vehicles (ROVs) have played an increasingly important role in the construction and monitoring of underwater pile foundations. However, due to the open frame structure of such vehicles, a gap of knowledge still exists with regard to their hydrodynamic behavior. In this study, the hydrodynamic stability of such vehicles is investigated numerically by means of a multiple reference frame method. The hydrodynamic characteristics of the ROV when it moves horizontally and upward in the vertical plane are examined. It is found that there is interference between the horizontal and vertical thrusters of the ROV. There is also interference between the propeller thrust and drag (or lift). The effect of the vertical thrusters can increase the horizontal thrust by about 5%. The horizontal thrusters create a low-pressure area below the body, which can make vertical drag experienced by the ROV significantly higher.

“…Regarding the hydrodynamic analysis of combining a robot frame and thrusters, Zhang et al [22] utilized a volume force model to simulate the interaction between the propeller and the ROV. They solved for the forces acting on the ROV when equipped with two or four screw propellers, considering horizontal and vertical motion, as well as propeller thrust and shaft torque.…”

Remotely operated underwater vehicles (ROVs) have been widely used in deep-sea resource exploitation and industrial engineering operations. To perform these tasks accurately in the deep-sea environment, stable motion control has become a key area of research on ROV systems, which has led to the importance of analyzing the hydrodynamic characteristic of ROVs. But a systematic methodology for analyzing the hydrodynamic characteristics of ROVs is still lacking nowadays. In this paper, systematic numerical simulation methods for analyzing hydrodynamic characteristics and shape optimization of a work-class ROV are conducted, and details of simulation procedures based on computational fluid dynamics are studied, which can be a foundation for robust controller design.

“…The flapping multifoil hydrodynamic model of gliders can be extracted through equations dependent on Reynolds-averaged Navier–Stokes (RANS) theorems, which work in ANSYS Fluent and other CFD programmes, respectively (Wang et al , 2019). Zhang et al (2019) applied the steady-state RANS method to estimate the stability and resistance of a remotely operated underwater vehicle (ROV) in simulations. Jagadeesh et al (2009) conducted experimental tests in a towing tank developed to measure the active moments and forces exerted on an AUV body in the vertical direction.…”

Purpose The development of robust control algorithms for the position, velocity and trajectory control of unmanned underwater vehicles (UUVs) depends on the accuracy of their mathematical models. Accuracy of the model is determined by precise estimation of the UUV hydrodynamic parameters. The purpose of this study is to determine the hydrodynamic forces and moments acting on an underwater vehicle with complex body geometry and moving at low speeds and to achieve the accurate coefficients associated with them. Design/methodology/approach A three-dimensional (3D) computer-aided design (CAD) model of UUV is designed with one-to-one dimensions. 3D fluid flow simulations are conducted using computational fluid dynamics (CFD) software programme in the solution of Navier Stokes equations for laminar and turbulent flow analysis. The coefficients depending on the hydrodynamic forces and moments are determined by the external flow analysis using the CFD programme. The Flow Simulation k-ε turbulence model is used for the transition from laminar flow to turbulent flow. Hydrodynamic properties such as lift and drag coefficients and roll and yaw moment coefficients are calculated. The parameters are compared with the coefficient values found by experimental methods. Findings Although the modular type UUV has a complex body geometry, the comparative results of the experiments and simulations confirm that the defined model parameters are accurate and close to the actual experimental values. In the proposed k-ε method, the percentage error in the estimation of drag and lifting coefficients is decreased to 4.2% and 8.39%, respectively. Practical implications The model coefficients determined in this study can be used in high-level control simulations which leads to the development of robust real-time controllers for complex-shaped modular UUVs. Originality/value The Lucky Fin UUV with 4 degrees of freedom is a specific design and its CAD model is first extracted. Verification of simulation results by experiments is generally less referenced in studies. However, it provides more precise parameter identification of the model. Proposed study offers a simple and low-cost experimental measurement method for verification of the hydrodynamic parameters. The extracted model and coefficients are worthwhile references for the analysis of modular type UUVs.
