摘要: 以双通道交叉射流喷嘴为射流源,在直径1000mm、高4000mm的大型冷模装置上,测定了射流携带床气化炉内的冷态浓度分布,考察了喷嘴环隙和中心射流动量比对宏观混合过程的影响;给出了无量纲径向浓度分布、无量纲最大浓度和混合分数的轴向衰减以及无量纲浓度半半径沿轴向的变化规律。

Abstract: In this paper, the concentration distribution of jet - entrained gasifier is measured in a large scale cold model (1000 mm ×4000 mm) gasifier based on the twin - fluid concentric intersective jet nozzle. The effect of the momentum ratio of annular jet to concentric jet on macro - mixing process is also investigated. The variation of dimensionless concentration, dimensionless maximum concentration, centre mixing fraction and dimensionless concentration half - radius is proposed.
