The objective of this Symposium is to provide a forum for researchers from universities, research institutes and industry to get together to discuss problems and share experiences involved in making measurements in turbomachines. The symposium covers the development of measurement techniques for the study of aerothermal phenomena in components such as cascades, compressors, turbines, engines and power plants.

Papers given at the conference concentrated on the development and experimentation of measurement techniques by turbomachinery researchers. Emphasis is given on the development of novel measurement techniques rather than the discussion of experimental data, experimental facilities or standard measurement equipment except where they are used to demonstrate the advantages/disadvantages of the measurement technique.

The Eighteenth Symposium on Measuring Techniques in Turbomachinery was held on 21st and 22nd September 2006, at the Aristotle University of Thessaloniki, Greece. Fifty participants have attended the Symposium and eighteen papers were presented. The long tradition of the Symposium on Measuring Techniques in Transonic and Supersonic Cascades and Turbomachines shall be continued in the years to come, under the new title.

The Symposium topics included:
The development of new experimental measurement techniques:
Optical techniques, heat-transfer measurements, high frequency measurements, MEMS.
New techniques for monitoring engine operation and performance:
High temperature instrumentation, emissions monitoring, measurement of engine deterioration and life, performance measurement.
The application of new analysis techniques to experimental data:
Optimisation of data analysis, application of new mathematical methods to experiments.
