基于CFD的船舶双螺旋桨水动力性能分析
|
摘要
目前,采用双螺旋桨的船舶较为广泛,但是由于船桨之间的相互干扰,造成螺旋桨水动力性能存在差异。本文以某型船舶双螺旋桨作为研究对象,基于滑动网络技术,采用ICEM软件建立螺旋桨的三维模型,采两种不同的湍流模型,分析了湍流模型对螺旋桨水动力性能的影响。采用对称边界模型对双螺旋桨进行数值计算,与单螺旋桨进行对比分析,双螺旋桨提升了推进效率。
At present, the ship with dual-propeller widely, but due to the mutual interference between the oars, causing the hydrodynamic performance of the propeller are different. In this paper, the three-dimensional model of dual-propeller would build by ICEM software and sliding mesh. The Fluent software was used to predict the hydrodynamic performance of dual-propeller. The effect on hydrodynamic performance by different turbulent model was analyzed, between k-ε and k-ω.The propulsion efficiency of dual-propeller was higher compare to single propeller by numerical calculation using symmetrical boundary model.
