摘要：
In this article, we demonstrate combined measurements of particle image velocimetry (PIV) and Multi-colour Integrated Cassegrain Receiving Optics (MICRO) in an attempt to observe characteristics of propagating flame in a premixed-spray stream. High-speed images recorded with an intensified CCD camera and cross-correlation PIV method showed the capability in obtaining instantaneous velocity fields in sooty spray flames, where liquid fuel of kerosene was supplied in the form of premixed spray. It enabled us to discuss the influence of fluid turbulent motion on the process of preferential flame propagation. Local chemiluminescence in flames detected by MICRO system was conditionally processed in terms of the distance from the spray boundary that was determined from visualized spray images. The time-averaged one-dimensional structure obtained statistically in the direction of flame propagation showed that two distinct reaction peaks appeared on both sides of the spray boundary, which corresponded to the main vaporization region of a spray.
