Vortical flows are an inevitable feature of almost all flow fields of aeronautical interest. For example, they arise from leading and trailing edges of wings, from bodies at high angles of attack and are always evident in separated flows. They can have major effects on the loading of surfaces with which they interact. They are sometimes stable and well ordered and their effects can then be beneficient and exploitable, but when unstable their effects are generally adverse. To expand the flight envelopes and controllability of modern aircraft we need to improve considerably our understanding of such flows as they are at th root of many important design problems. The Symposium was divided into five sessions with the following topic headings Fundamental Generation and Structure of Vortical Flows, Interaction of Vortical Flows with Surfaces, Modelling and Computing, Stability and Breakdown of Vortical Flows, Control and Exploitation of Vortical Flows. The papers showed that in all the main areas of interest considerable progress has made in recent years, but much remains to be done. We have a good topological basis for describing separated flows and the associated vortical flow regions the computation of inviscid models e.g. panel methods, Euler equation solutions, convected vortex element methods is developing well and practical forms of control and exploitation have been sucessfully demonstrated.
