Abstract: Aiming at the problem of fatigue failure of underwater gas storage device under the influence of ocean current in complex marine environment, the hydrodynamic characteristics of underwater gas storage device were studied by combining model experiment with numerical simulation. Firstly, the balloonshaped gas storage device was selected as the research object, the scale model of the gas storage device was designed according to the similarity principle, and the hydrodynamic experiment was carried out. Then, the large eddy simulation (LES) method was used to simulate the gas storage device, and the flow field structure and force characteristics were analyzed. Finally, the reliability of the numerical simulation results was verified by comparing the numerical simulation results with the experimental results.The results show that the vortex structure of the balloon-shaped gas storage device is complex and the scale is rich, and there are obvious Karman vortex streets behind the device. The average drag coefficient and lift coefficient are stable at 0.09 and 0.04 at the flow rate of 0.4m/s. The results describe the hydrodynamic characteristics of the balloon-shaped underwater gas storage device in the complex marine environment, and provide a theoretical basis for the optimal design of the gas storage device.
