In recent years there has been a marked growth in the applications of vortex dynamics to time-varying flows, usually involving separated regions with vortical structures. The flow models are based on distributions of vortex elements which may vary in complexity. This report is a compilation of invited papers which cover current and projected developments in France, Germany, Greece, Italy, Netherlands, UK and USA. The report provides a good overall view of the state of the art of the topic, covering both the achievements and the deficiencies requiring future research. The outstanding problems centre on how the effects of viscosity can be done to deal with the effects of compressibility. However, methods based on vortex dynamics seen particularly suited to problems involving well defined, large scale vortical flows which they provide a more direct physical insight into the nature of the flow than other methods.
