Analysis of aero-optical distortions based on canonical correlation analysis and proper orthogonal decomposition

  • 摘要: 利用典型相关分析和本征正交分解方法,对计算流体力学得到的导弹红外窗口绕流三维密度场数据进行研究.取三维密度场沿展向两个相邻截面的数据先进行典型相关分析提取出两个截面的相关性最强部分,再利用本征正交分解消除两个截面之间数据的冗余信息,获得了能够包含两个截面密度场主要的信息部分.利用提取出的数据重构流场,并进行气动光学畸变仿真分析,仿真结果能较好地近似原始流场的情况.
