【摘要】 采用RNG(重整化群)k ε模型对旋喷结合分解炉内的气相流场进行了数值模拟,通过改变分解炉的中部缩口尺寸、上部柱体尺寸和下部柱体尺寸的结构参数以及入口气流的流速,在不同条件下得到了炉内的流场分布情况,并进行了比较和分析,为分解炉的结构优化设计提供了参考依据.更多还原

【Abstract】 A numerical simulation of flowfield in the spiraled and sprayed precalcier based on RNG kε model was introduced.Under different conditions, different flowfields can be obtained by changing the construction parameters of the middle necking, upcylinder and undercylinder and the velocity of entrance boundaries.The compared and analyzed results can supply references and information for optimization of flowfields and constructiondesign of the precalciner.更多还原
