LIF喷流混合流浓度场定量测量
LIF QUANTITATIVE CONCENTRATION FIELD MEASURE-MENT FOR THE MIXING FLOWS OF FREE JETS
-
摘要:本文介绍激光诱导荧光(LIF)的瞬时浓度场定量测量技术,采用了CCD图象采集处理系统和低浓度简化校正技术等,讨论了喷流混合流浓度场测量的初步结果。Abstract: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.
