摘要

摘要: 通过对涡轮多学科优化的分析,讨论了多学科优化中的气动设计技术.提出了基于叶栅特征参数和贝塞尔函数的二维叶栅参数化造型方法,并结合积叠轴的掠、弯形成三维复杂几何叶片成型技术.通过对气动优化过程中的数学模型分析,给出了一般要求的约束条件,并根据不同阶段的气动设计和约束条件提出了分阶段嵌套优化方法.针对三维气动计算,对商用软件CFX进行了二次开发,实现了三维计算的自动分网、建模、求解和后处理.最后,结合具体算例完成的优化设计结果表明,其涡轮效率提高了约2.3%,工作叶片数减少13.21%,叶片叶身总质量下降8.96%.

Abstract: Aerodynamic design technology in multidisciplinary optimization was discussed in this paper through the analysis of multidisciplinary design optimization (MDO) for turbine.Complex three-dimensional (3-D) blade profile generation technique was proposed by incorporating the swept stacking axis method and a two-dimensional cascade parametric modelling method based on cascade characteristic parameters and Bezier spline.General restrictions were given through the analysis of the mathematic model used in aerodynamic optimization.And an optimization method was also proposed according to the aerodynamic design and restrictions at different stages.For 3-D aerodynamic simulation,tgrid generation,modelling,solving and post processing can be completed automatically by further programming based on CFX.The optimization results show that an increase of 2.3% in turbine efficiency has been reached,the number of rotating blades reduces by 13.21% and the overall mass of blade decreases by 8.96%.
