Abstract：Using the standard k‐ε model ,with fluent dynamic meshes ,this paper siumulates the hydrodynamic pressure field stimulated by a moving submarine .Basing on the simulation ,a new discrimination method of the hydrodynamic pressure field is rised .The result demonstrates that the distribution of hydrodynamic pressure field seems like a horse saddle .The negative pressure distribution length is approximately one times of the captain length .While the extreme negative value of the pressure field ,which is the characterization of submarine pressure field strength ,has linear relationship with the flow dy‐namic pressure ,and significantly varies with the speed and depth of the submarine ,the distribution of hydrodynamic pressure field pressure coefficient only changes with the diversification distance of submarines and seabed .r when the voyage depth is constant ,the distribution will not change with speed .The new method based on the combination of the duration of negative pressure and voyage speed provide can effectively judge on a high speed target .
