SOME DISCUSSION ON PIV - ONE OF APPROACHES OF 'FFFOM' FACING 21st CENTURY FOR FLUID MECHANICS

摘要

As the one of the approaches to so called Ideal Observation & Measurement Technique (IOMT ) for the fluid mechanics and the most practical one of Full Flow Field Observation and Measurement techniques ( FFFOM ) which will be the new generation of the experimental technique or instrumentation to across the new century, the recent progress and trend of Particle Image Velocimetry ( PIV ) & its application ( including some work in China ) was summarized and evaluated in some aspects. Also the facing requirements and further work of PIV for the complex & turbulent flows and the industrial applications was discussed. It will be the challenge for the PIV to face 21st century.
