摘要：

In order to master the influence of ice ridges on the hydrodynamic characteristics of submarine sailing near the ice surface, the subglacial channel near the ice surface flow field composed of three groups of equally spaced ice ridges is established for the SUBOFF submarine model with KP505 propellers. The hydrodynamic research method of self-propelled submarine combined with overset mesh and sliding mesh is utilized to predict the self-propelled characteristics of a full-appended SUBOFF submarine with KP505 propeller under continuous ice ridge, and the hydrodynamic coupling mechanism between ice ridge and self-propelled submarine is analyzed. It is found that the propeller speed of submarine under continuous ice ridge is about 11% lower than that under flat ice ridge. When the submarine is sailing near the ice ridge, the resistance is always vibrating near the mean value, and the oscillation amplitude is about 10% of the mean value. When the submarine passes through the ice ridge, the surface pressure coefficient increases and the thrust coefficient decreases. © 2023 Editorial office of Ship Building of China.
