In order to meet the needs of the evaluation and optimization of submarine near-surface navigation performance, this paper performs a numerical study on the hydrodynamic characteristics of a near-surface self-propelled submarine by using Reynolds-Averaged Navier-Stokes method. The volume of fluid model is used to capture the interaction between submarine and free surface, and the body force model is used to establish the propeller hydrodynamic model. At the same time, the controllers of propeller and stern rudders are constructed to control the speed and course of the submarine, and the numerical simulation of the submarine near-surface self-propulsion test is realized. The numerical simulation results are compared with the model test data and numerical simulation results from other literature, and the effectiveness of the established numerical method is thus verified. Through the numerical simulation of the submarine self-propulsion test under different immersion depth, the variation law of the submarine near-surface self-propulsion point with the immersion depth is revealed, and the internal mechanism is discussed by combining the flow field characteristics obtained from numerical simulation.
