Investigation of Normal Force and Moment Coefficients for an AUV at Nonlinear Angle of Attack and Sideslip Range

Hydrodynamic Analysis of AUV Hulls Using Semi-empirical and CFD Approach

“…Nahon [8], [9], was the first researcher to model his ARCS AUV using the airship theories mentioned above. Similar work was carried out by, Prestro [10], Perrault [11], Evans [7], Barros et al [12] etc.. The range of angle of attack up to which these equations can predict the hydrodynamic forces and moments with reasonable accuracy on the AUV hull is still unknown.…”

Predicting the wake behind a large AUV hydrofoil

“…Our application of CFD was relatively superficial compared to other studies that have used CFD to numerically model the flow around AUVs and particularly for investigating its wake (Falcao de Campos, 1983;Tyagi and Sen, 2006;Phillips et al, 2007;de Barros et al, 2008;Wu, 2010;Vaz et al, 2010). The authors thank an anonymous reviewer for providing these references.…”

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].…”
