Abstract

The Reynolds-averaged Navier–Stokes (RANS) equation was solved using computational fluid dynamics to study the effect of the circulating tank wall on the hydrodynamic coefficient of an autonomous underwater vehicle (AUV). Numerical results were compared with the experimental results in the circulating water tank of Harbin Engineering University. The numerical results of the model with different scale ratios under the same water in the flume were studied to investigate the effect of blockage on the hydrodynamic performance of AUV in the circulating flume model test. The results show that the hydrodynamic coefficient is stable with the scale reduction of the model. The influence of blocking effect on AUV is given by combining theoretical calculation with experiment.

Article Highlights

• In order to study the effect of blockage on the hydrodynamic performance of underwater vehicle in the model test of circulating tank, it is necessary to analyze the hydrodynamic performance by combining numerical and experimental methods.

• The hydrodynamic performance of the model in the circulating tank is calculated and the hydrodynamic values under different working conditions were obtained.

• The hydrodynamic performance of three models with different scale ratios is studied and the influence of blocking effect is obtained.

• The results of numerical calculation are verified by experiment, which proves the accuracy of numerical calculation of hydrodynamic force.
