Symposium on Advanced Flow Management. Part A: Vortex Flows and High Angle of Attack for Military Vehicles. Part B: Heat Transfer and Cooling in Propulsion and Power Systems

The principal emphasis of Vortex Flows and High Angle of Attack for Military Vehicles in this symposium is on the understanding and prediction of separation-induced vortex flows and their effects on vehicle performance, stability, control, and structural design loads. In nine sessions the subject was highlighted based on recent and current research and developments for flows with vortical type separation to enhance the overall vehicle performance. Heat Transfer and Cooling in Propulsion and Power Systems was focussed in a complementary way on the internal flow stream control. Propulsion and power systems, for land, sea, and air are normally based on thermal energy cycles as gas turbines, piston engines and rockets. Growing cycle temperatures place severe demands on gas path components and require new and improved cooling technologies for engine components (a.o. compressors, combustors, turbines). Particular emphasis is also put on advanced cooling concepts to meet the demands of lean low emission combustion in transport vehicle engines. The Symposium brought together specialists from Industry, Universities and Research Institutes. It highlighted progress achieved since the last AGARD activities on the subject of the meeting by covering numerical and experimental work as well as flow visualization and in-flight testing. New developments in military applications at industry have been addressed by excellent review papers given from leading industries and research institutes involved. Technological gaps have been identified and trends for future developments were assessed in two technical evaluations at the end of the symposium as a mature basis for future research work and technical applications.
