动网格技术在增升装置优化中的应用

摘要

将基于Denaulay背景图的动网格方法应用于增升装置二维缝道参数优化设计过程中。针对二维增升装置的构型特点和翼型运动的特点，采用了添加辅助点的双层Denaulay背景图动网格方法，并详细论述了辅助点添加、运动技术。为了进一步提高动态网格质量，提出了针对前后缘运动位置中比较极端的两种位置生成两个初始网格，并采用两种初始网格进行动态网格的生成。结果表明新动态网格方法可以为二维增升装置提供高质量的动态网格。%Dynamic mesh method based on Delaunay graph is applied in 2-dimesion high-lift device pa-rameter optimization. For the characteristics of 2-dimesion high-lift device and its movement,dynamic mesh technology of double layer Delaunay graph with auxiliary points is used. To further enhance the dy-namic mesh quality,a method that dynamic meshes are generated on two kinds of initial meshes which are based on extreme slat/flap moving position is proposed. The results indicate that dynamic method in this paper can generate high quality dynamic meshes for 2-dimension high-lift device.
