“…The hydrodynamic coefficients are useful in the development of the control system of the AUV. Song et al 36 performed numerical simulations on flow past a Myring shaped AUV using k − ω SST turbulence model. The resistance of the complex hull was calculated using numerical simulations.…”

Autonomous underwater vehicles play an essential role in geophysical data collection, deep water mining, seafloor mapping, ocean exploration, and in many other related activities starting from military to scientific applications. A detailed understanding of hydrodynamic characteristics will lead to better design, better control, and optimal path planning of autonomous underwater vehicles in the deepest corner of oceans. This article will provide a detailed review of the hydrodynamic characteristics of autonomous underwater vehicles, starting from different experimental techniques used in the analysis of hydrodynamic parameters, methods used for fixing the autonomous underwater vehicles in towing tank, instruments used for measurement of the hydrodynamic parameters. Furthermore, numerical methods employed in performing computational analysis, hydrodynamics-based shape optimization, studies on drag reduction, and finally a detailed list of turbulence models used in the computational fluid dynamics–related numerical simulations. The hydrodynamics-based optimal shape of the autonomous underwater vehicles, the best technique to predict the hydrodynamic parameters, and the best turbulence model for the computational fluid dynamics–based prediction of hydrodynamic parameters will be recommended. At last, the hydrodynamic characteristics of different bio-inspired autonomous underwater vehicles are discussed.

“…3 Hence, in the early stage of designing AUVs, the reduction of body resistance is one of the key objectives of design. 4 So far, many numerical studies have been conducted to calculate drag of underwater vehicles. Karim et al 5 have numerically quantified viscose drag using a finite-volume method based on the Reynolds-averaged Navier–Stokes equations on DREA submarine hull and six axisymmetric bodies.…”

In this research, the flow around the autonomous underwater vehicles with symmetrical bodies is numerically investigated. Increasing the drag force in autonomous underwater vehicles increases the energy consumption and decreases the duration of underwater exploration and operations. Therefore, the main objective of this research is to decrease drag force with the change in geometry to reduce energy consumption. In this study, the decreasing or increasing trends of the drag force of axisymmetric bare hulls have been studied by making alterations in the curve equations and creating the optimal geometric shapes in terms of hydrodynamics for the noses and tails of autonomous underwater vehicles. The incompressible, three-dimensional, and steady Navier–Stokes equations have been used to simulate the flow. Also, k-ε Realizable with enhanced wall treatment was used for turbulence modeling. Validation results were acceptable with respect to the 3.6% and 1.4% difference with numerical and experimental results. The results showed that all the autonomous underwater vehicle hulls designed in this study, at an attack angle of 0°, had a lower drag force than the autonomous underwater vehicle hull used for validation except geometry no. 1. In addition, nose no. 3 has been selected as the best nose according to the lowest value of stagnation pressure, and also tail no. 3 has been chosen as the best tail due to the production of the lowest vortex. Therefore, geometry no. 5 has been designed using nose and tail no. 3. The comparison made here showed that the maximum drag reduction in geometry no. 5 was equal to 26%, and therefore, it has been selected as the best bare hull in terms of hydrodynamics.
