艇桨及外挂吊舱之间水动力性能干扰分析
Interaction of hydrodynamic performance between body propeller and appendages of small autonomous underwater vehicles
摘要
Abstract
Based on computational fluid dynamics(CFD) technique,the hydrodynamic performance of the body,propeller,body with appendages,the body with propeller,and the body with propeller and appendages were simulated numerically by RNG k-ε turbulent model and hybrid grid.The hydrodynamic interaction between body,propeller and appendages were analyzed.The calculation results show that the influence of appendages on the body resistance and propeller thrust is small.In the detect sailing,the body with appendages model produce pitching moment,lift,and the body resistance is reduced because of the existing of appendages.The distribution of pressure on the surface of the body is greatly influenced by the interaction between the body and propeller;the body resistance is increased 18.03% in the body with propeller model and the body with appendages increase 17.63% in body with appendages and propeller when the propeller is working at the uniform velocity of 1.5 m/s.关键词
