Abstract
A fluorescence image detection system that can visualize the COIL hot mixing flow field by taking images of the fluorescence of active I2 with a high speed camera was set up. Based on the captured flow field image, O2(a1Δ)/I2 mixing quality was evaluated quantitively by an exclusive image processing program. With this method, the hot supersonic mixing flow field in COIL which uses parallel stream supersonic mixing nozzles with a set of trip tabs was investigated. Meanwhile the effectiveness of the trip tabs was demonstrated.
