The Aerodynamics of Reacting Substances [PDF]
Proceedings of the National Academy of Sciences, 1939 Speaking broadly, the subject of aerodynamics is concerned not only with the forces exerted by a single fluid on solid bodies but also with the behavior of mixtures such as those which occur in the gasoline engine and in the atmosphere. In a complete study of the motion of a fluid attention must be paid to reactions between its constituents ...

A High Efficient Fluid-Structure Interaction Method for Flutter Analysis of Mistuned [PDF]
Xibei Gongye Daxue Xuebao, 2018 The time cost is very high by direct fluid-structure interaction method for mistuned bladed disk structures, so aerodynamic loads generally are ignored or treated as small perturbations in traditional flutter analysis.
