Abstract: The influence of propeller thrust performance on the stability control and safety performance of autonomous underwater vehicle (AUV) during the process of AUV recovery is very obvious. Based on CFD method, the multi-block meshes method combined with RNG k-ε turbulent model is used for the simulation of propeller thrust performance of AUV in different recovery cases. The three-dimensional geometric models of AUV and propeller are built. The calculation domain is dispersed by multi-blocks meshes, and the dynamic mesh technique is used to simulate the motion of AUV and propeller. The numerical simulations are performed based on the finite volume method. The comparison of numerical and experimental results,as well as numerical independence test show that the proposed numerical method can be used to calculate the propeller thrust performance during the process of AUV underwater recovery accurately, and the numerical results can provide theoretical reference to the stability control and safety performance of underwater AUV recovery.
