Unsteady Aerodynamic Phenomena in Turbomachines

Abstract

The Specialists' Meeting was arranged in the following sessions: Flutter or Oscillating Cascades (5); Wakes or Complete Stage (10); Transonic and Supersonic Unsteady Phenomena (4); and Experimental Studies and Instrumentation Problems (5). The Technical Evaluation Report is included at the beginning of the Proceedings. Questions and answers of the discussions follow each paper. While around isolated airfoils many results on unsteady aerodynamic phenomena are available, reliable experimental data for unsteady turbomachinery flows were still missing. Therefore, the Specialists' Meeting offered a forum for experts to discuss the degree of advancements in this field. It was found that CFD with large numerical codes will be more and more developed and offer a useful tool for designers to improve their products. The experimental work for code validation is lagging somewhat behind. Keywords: Blades; Cascade; Compressors; Flutter; Oscillation; Supersonic flow; Transonic flow; Turbines; Unsteady aerodynamic; Vibration; Wakes; Symposia; Turbomachines.
