N2 - Autonomous underwater vehicles (AUVs) have been widely used in many aspects of the underwater world for their autonomy and robust flexibility. However, the dynamic performance of the small AUVs is strongly affected by hydrodynamic effects. In this work, based on a novel designed small AUV, we conduct a hydrodynamic coefficients estimation work by adopting the computational fluid dynamics (CFD) method. Firstly, the resistance to AUV under different propeller layout conditions is analyzed. Secondly, to study the hydrodynamic coefficients of the AUV at different pitch angles, we simulated the movement of the AUV in the Fluent module and determined the thrust of the propeller by estimating the axial and radial forces. Simulation results show that the resistance and sinking force coefficients of the designed AUV are positively correlated with pitch angle and negatively correlated with Reynolds number. This work provides a vital reference for designing effective control strategies for small underwater vehicles.
