In this study, numerical computation is used to develop a physical model representing all important features of the Autonomous Underwater Vehicle's (AUV) shape using the finite element methods. Because the shape of the AUV is an essential factor in determining the application and the vehicle's capability, investigating the effect of the environment...

... reality, AUVs are high maneuverability that can move in any direction. Figure 7 illustrates the effects of fluid on the profile when the AUV moves in the inclined direction with a 45 degrees angle and the velocity is equal to 2.0 m/s. According to the numerical results in Figure 7, the nose of the AUV occurs the highest value of pressure (4.12 x 10 −4 Pa), similar to the previous case when the AUV moves horizontally. ...

This study aims to design a new hybrid twin autonomous underwater vehicle (HTAUV) consisting of dual cylinder hulls and analyze its pitching motion. The kinematic model for the HTAUV is established, followed by the execution of hydrodynamic simulation CFD of the HTAUV using Ansys Fluent. These simulations are conducted to obtain the hydrodynamic force equation of the HTAUV, which relates to the deflection angle of the elevator. Through the motion simulation of the HTAUV, under the same net buoyancy condition, notable differences emerge when the elevator is deflected. Specifically, parameters such as gliding speed, gliding angle, and pitch angle of the HTAUV are larger when the elevator is deflected, as compared to cases where no deflection is applied.
