Unsteady separated flows over three-dimensional slender bodies

Abstract Many review articles have been written on the topic of the aerodynamics of slender bodies at incidence, some of which are referenced in this paper. Here, we review the unsteady behavior of these flows. Our aim is to review the material that contributes to our understanding of unsteady phenomena over slender bodies at incidence. Natural unsteadiness is explored first. Unexpectedly, we found a large number of contributions in this area. We found the material disjointed, making it difficult to draw general conclusions. Forced unsteadiness is conceptually easier to follow, but the number of contributions on this topic is much smaller. We consider both experimental and numerical contributions but we do not discuss the corresponding methodologies.
