LOSS MECHANISMS AND UNSTEADY FLOWS IN TURBO MACHINES The Propulsion and Energetics Panel of the Advisory Group for Aerospace Research and Development (AGARD) will hold a Symposium on ``Loss Mechanisms and Unsteady Flows in Turbomachines'' from 8-12 May 1995 in Derby, United Kingdom. The symposium focuses on a better understanding of loss mechanisms and general flow characteristics for optimizing turbomachinery efficiency and pave the way for improved design and analysis techniques. Topics to be discussed include boundary layer transition, separation and post-separation behavior, shock/boundary layer interactions, clearance effects, surge and stall, and secondary flows, especially at off-design and unsteady periodic conditions. For further information, contact the AGARD National Coordinator, Lt Col Stephen Marino at 703-602-7358, fax 703-607-3158, e-mail to MARINOS@ SAF-IA.HQ.AF.MIL, or write to the local PEP Coordinator, Mr. Joseph A. Ziemianski, Chief, Propulsion Systems Division, Aeronautics Directorate, NASA Lewis Research Center, 21000 Brookpark Road, Cleveland, OH 44135.
