Abstract

The flow field model of underwater vehicle with pump jet propulsion was established based on multiple reference frame (MRF). RANS equations with k-εRNG turbulent model were solved by FLUENT software to simulate the flow field. Validity of the CFD model was verified using data from experiment. Through analyzing the flow field, it is found that drag coefficient at 10m/s increases by 47 percent under the influence of pump jet propulsion. Lift coefficient and pitch moment coefficient change less than 3%. The simulation method and CFD results could provide an important reference for later research on hydrodynamic characteristics of underwater vehicle with pump jet propulsion.

Key words： pump jet propulsion; flow field with power; hydrodynamic characteristics; MRF
