Prediction of submarine buoyancy motion is a prerequisite for exploring the characteristics of submarine control and safety. The present article thoroughly describes the numerical method and calculation procedure for the simulation of submarine buoyancy motion. The turbulence model and numerical discretisation scheme are described. The uncertainty of numerical calculations is analysed and the numerical results are verified based on the buoyancy test. The reliability of the numerical method is confirmed. Furthermore, the numerical calculation results are in good agreement with the experimental results, verifying the feasibility of the numerical method. The effect of positive buoyancy, the longitudinal position of the centre of gravity and diving depth on the submarine buoyancy are studied. The numerical scheme, test method and related conclusions can provide technical support for the research on submarine buoyancy.
