Rapport d'Evaluation Technique du Congres du Panel de la Dynamique des Fluides sur la Mise en Oeuvre de Moyens non Perturbateurs D'etude des Ecoulements des Fluides(Evaluation Technique Report of the Fluid Dynamics Panel Symposium on Applications of Non-Intrusive Instrumentation in Fluid Flow Research).

摘要

The FDP symposium provided a survey and review of non-intrusive measurement concepts, particularly the laser doppler anemometer. Application of laser anemometry and Raman diffusion techniques in research facilities has become commonplace. These research tools require specially trained operating personnel who often are the aerospace engineer or aerodynamicist himself. These techniques are widely used in simple cases for obtaining data at a single measurement point, but their usage is extremely difficult in complicated, three dimensional flow configurations and close to a wall. Basic problems include the restriction of optical access to the test field, the tedious time consuming process of obtaining local point measurements, measuring accuracies and corrections, and interpretation of results. In the future, these measurement techniques will become indispensable in both research and industry. The Proceedings of the AGARD Fluid Dynamics Panel Symposium on Applications of Non-Intrusive Instrumentation in Fluid Flow Research are published as AGARD CP-193. (Author)
