Computational Aerodynamics Methods

  • P. G. Tucker
Part of the Fluid Mechanics and Its Applications book series (FMIA, volume 104)


An overview of the various unsteady modelling hierarchies in aerospace is given ranging from linear harmonic to direct numerical simulation. Unsteady reduced order modelling encompassing deterministic stresses and body forces are discussed. Hierarchies are presented for different modelling lineages and fidelity levels. Mixed fidelity methods are proposed, where low and high fidelity treatments are combined. For example, URANS being combined with body forces to provide appropriate system boundary conditions. This concept is extended further in later chapters. For URANS, the occurrence of a spectral gap in many turbomachinery zones is found to be uncertain. The wide range of other aspects needed to model aeronautical flows and their limitations is discussed.
