  • 摘要: 利用计算流体力学方法对减摇鳍与船体之间的适配性问题进行研究。利用零航速减摇鳍的参数以及某型驱逐舰的船型型值表,分别建立在敞水条件下的减摇鳍模型以及加上减摇鳍的船体模型。首先,仿真分析在中、高航速下敞水条件的减摇鳍与受船体约束减摇鳍的静态水动力特性。其次,利用动网格技术分别分析在中、高航速和低航速下敞水条件的减摇鳍与受船体约束减摇鳍的动态水动力特性。计算结果分析表明:静态仿真时,虽然受船体约束减摇鳍的失速角没有敞水条件下的减摇鳍大,但在同样的攻角下,其升力系数却有较大的提高; 在动态仿真中,无论是在中、高航速还是低航速下,受船体约束减摇鳍拍击产生的升力都要比敞水条件下的减摇鳍大,但同时产生的阻力以及所需的转鳍力矩也有较大的提高。
    Abstract: This paper uses the computational fluid dynamics method to analyze the suitability of stabilizer fins and the hull. An isolated fin model under open water condition and the model of the fin added on the hull are set up, using the parameters of a zero-speed fin and the dimension parameters of a destroyer ship model. Firstly, the static hydrodynamic characteristics of the isolated fin model and the model of the fin added on the hull under high speed are simulated and analyzed. Secondly, the dynamic hydrodynamic characteristics of the isolated fin model and the model of the fin added on the hull under high speed and low speed are studied via a dynamic mesh method. The results show that when the fins are added on the hull, the lift coefficient is greatly improved, even though the stall angel of the isolated fin at the same angel of attack becomes larger. Also, in both high speed and low speed conditions, the added fins produce better results than isolated fins, yet at the same time the resistance and the required torque becomes lager. In brief, this paper provides a reference for further discussion involving the hydrodynamic performance of fins.
