Hydrodynamic Analysis of the Autonomous Underwater Vehicle by Implementing Computational Fluid Dynamics Method

Abstract

The purpose of the study was to analyze Autonomous Underwater Vehicle (AUV) by using Computational Fluid Dynamics (CFD) to export the AUV in the full appendage in the flow field The numerical simulation of the turbulence model uses the SST k-ω model (Shear Stress Transport K-ω model) as the current turbulence model and SIMPLEC (Semi-Implicit Method for Pressure-Linked Equations Consistent) as the setting condition for the solver and refers to DAPA SUBOFF's experimental plan for the Oblique Towing Test Simulations of various inflow angles (β) and pitch angles (?) were conducted to analyze the changes in the forces and moments that the AUV is subjected to Simultaneously the flow field difference pressure distribution flow field variation pressure coefficient and friction coefficient distribution of the AUV under different inflow angles and pitch angles were observed
