摘　　要：该文开发了一种基于定常计算的导管螺旋桨自动优化设计技术。该方法综合了导管桨桨叶、导管及桨毂的几何生成、网格自动划分、优化算法和CFD分析等技术,有助于将螺旋桨理论计算推广到设计阶段。文中采用该方法计算某导管螺旋桨的改造,并与试验结果进行了比较,验证了其效果。计算结果显示,优化后的导管桨可以提供更高的推力和效率。In this paper, a design technique based on steady analysis of ducted propeller is presented. The approach combines geometry generation, auto-meshing, optimization algorithm and CFD techniques that make the process automatically operated and extended the CFD analysis to the design stage. An upgrading project is performed for a case study to improve the efficiency of an existing ducted propeller. For the computation case, the optimized result can provide higher thrust force and efficiency than the ducted propeller installed on the vessel. The model test validated the results.
