In order to study the influence of oblique flow on the hydrodynamic analysis and flow field analysis of the ducted propeller for the underwater robot,based on the computational fluid dynamics method,this paper uses the sliding mesh technology to carry out the numerical simulation calculation on the system model of an autonomous underwater robot with a water drop streamline cylindrical structure.The results show that the thrust produced by the propeller will increase with the increase of the angle of oblique flow in a certain range;The oblique flow will lead to the nonuniformity of the wake field and the nonuniformity of the circumferential velocity distribution.The pressure nephograms of propeller also show a certain pattern of variation at different angles of oblique flow.
