ABSTRACT This paper demonstrates how, by means of Reduced Order Modelling (ROM), CFD cost can be drastically reduced and, in addition, a more complete investigation of a continuous design space obtained by adding experimental fluid dynamics (EFD) and flight fluid dynamics (FFD) data. The ‘Gappy’ Proper Orthogonal Decomposition (GPOD) method is used to enrich the EFD and FFD data to the size of their companion CFD. All three are then combined in a multidimensional database providing a much finer real-time exploration of a design space. Examples from aerodynamics and in-flight icing are given.

通过 Gappy 适当正交分解组合 CFD-EFD-FFD 数据

摘要 本文展示了如何通过降阶建模 (ROM) 显着降低 CFD 成本，此外，还通过添加实验流体动力学 (EFD) 和飞行流体动力学 (EFD) 对连续设计空间进行了更完整的研究。 FFD) 数据。'Gappy' 适当正交分解 (GPOD) 方法用于将 EFD 和 FFD 数据丰富到其伴随 CFD 的大小。然后将所有三者组合在一个多维数据库中，提供对设计空间的更精细的实时探索。给出了空气动力学和飞行中结冰的例子。
