摘　　要：采用CFD技术数值预报了二维智能水下机器人(AUV)回收过程中与潜艇之间的水动力干扰性能.首先数值计算了二维Rankine体近平壁面运动的水动力特性,分析了不同间距比对其所受壁面干扰力的影响,与试验结果符合良好.然后讨论了不同相对位置条件下AUV的阻力、升力以及倾覆力矩性能,对AUV在潜艇扰流流场下的压力分布进行了分析,实现了二维AUV与潜艇定常水动力干扰性能的预报.最后结合动网格技术,数值模拟了AUV在给定路径下靠近潜艇过程中的非定常扰动力性能,计算结果表明以上方法可为AUV回收中的操控性能提供预报.Hydrodynamic interaction performance between a 2D autonomous underwater vehicle （AUV） and a submarine was presented using computational fluid hydrodynamics （CFD） techniques, when a submarine was recovering an AUV. Firstly, hydrodynamic characteristics of a 2D Rankine while moving near plane wall were simulated numerically. Influence of different gap ratio on interac- ting forces was analyzed, and calculation results were in good agreement with the experimental val- ues. Then, the resistance, lift and moment of an AUV were investigated in different position relative to a submarine. The pressure distribution around an AUV was particularly analyzed in the submarine disturbing flow field. Prediction of steady hydrodynamics interaction performance between an AUV and a submarine was achieved. Lastly, combined with dynamic grid techniques, unsteady hydrody- namics performance was numerically simulated when an AUV was moving to a submarine on the given path. The method presented could predict the maneuvering and controlling performance of the AUV retrieved to a submarine.
