LIF QUANTITATIVE CONCENTRATION FIELD MEASURE-MENT FOR THE MIXING FLOWS OF FREE JETS
LIF喷流混合流浓度场定量测量

The instantaneous quantitative measurements of the concentration field using Laser Induced Fluoresence (LIF) technique with a Digital Image (CCD) capture & processing system and the simplified calibration for the free jet mixing flows are presented. Also some digital image process method used for better displaying the flow structures and some preliminary results are discussed.
