The horseshoe vortex is typical flow characteristic around the appendage-body junction. The horseshoe vortex formation around the hull-said junction has important influence on the submarine hydrodynamics performance. The origination process of the submarine horseshoe vertex and its influence on submarine flow is analyzed. The numerical simulation on the horseshoe vortex is carried out using DES method (Detached Eddies Simulation); the influence og model speed on submarine horseshoe vertex is studied. It is shown that the model speed has little influence on the position of the horseshoe vortex center, while has signification influence on the intensity of horseshoe vortex. The attenuation of horseshoe vortex becomes slow with the increase of its distance.
