摘要：
Definition of raceway shape and size has always been a challenging task. The whole physical parameters field can be used to describe the raceway boundary precisely, but all of the physical parameter fields are obtained from numerical simulation so far and there isn't a specific criterion to define the raceway boundary. In this study, a new digital image processing technology has been developed to define the raceway boundary in cold model of COREX melter-gasifier, so as in blast furnace, granular drying, etc. The particle velocity contour criterion of raceway boundary definition is 0.15 m/s in this study and the precise raceway boundary can be obtained through this method. It is very important for the theoretical and mathematical modeling of the gas and solid flow and chemical reaction in and around the raceway region.
