A study of autonomous underwater vehicle hull forms using computational fluid dynamics

Computation of Axisymmetric Turbulent Viscous Flow Around Sphere

“…Choi and Chen [2] gave calculation method for the solution of RANS equation, together with k-ε turbulence model. Sarkar et al [3] used a low-Re k-ε model of Lam and Bremhorst [4] for simulation of flow past underwater axisymmetric bodies.…”

Experimental validation of open-frame ROV model for virtual reality simulation and control

“…A dynamics model of an ROV for designing the GNC [1] is required. Unfortunately, the six degrees of freedom (DoF) dynamics model of the ROV [2][3][4][5] is harder to model than the streamlined autonomous underwater vehicle (AUV) [6][7][8][9][10][11][12][13][14][15] which exists an analytical solution for the hydrodynamics parameters.…”

“…However, this method is quite costly, time-consuming and subject to the availability of the test facilities and an adequate scale model. With the recent advancement in computer technology, the computational fluid dynamic (CFD) has been widely used for the URV [6,8,[12][13][14]16].…”

“…The following CFD software namely: ANSYS-FLUENT TM [16], ANSYS-CFX TM [12] and Phoenics TM [6] have been used. The CFD simulations have shown to be quite successful in simulating the streamlined underwater vehicles such as AUV but commonly performed on a complex-shaped ROV.…”

Hydrodynamic analysis of AUV underwater docking with a cone-shaped dock under ocean currents

“…Literature surveys on the hydrodynamics of underwater bodies reveal that the surveys may be limited to 2D (two-dimensional) bodies; simplified 3D bodies, such as balls or ellipsoids; or constant velocities, as shown by Dantas and Barros (2013), Phillips et al (2010) and Sarkar et al (1995). In this article, an AUV-like REMUS docking with a cone-shaped dock is simulated.…”
