ABSTRACT

The prediction of hydrodynamic performance of AUV is essential during the early stages of design for the efficient modeling of the AUV. This paper discusses the use of semi-empirical equations developed for airship hulls by various researchers in the field of aerodynamics, on the axisymmetric AUV bare hull at different angles of attack. Three hulls of varying length-to-diameter (L/D) ratios are selected for the study. The results obtained from the semi-empirical equations are compared with the available experimental results and also with the results obtained from the numerical analysis carried out using the CFD code – STAR CCM+.
