【摘要】 针对某分解炉的实际尺寸,采用Realizablek-ε模型,SIMPLE算法,二阶迎风差分格式,按两种不同的进口条件对炉内三维湍流流场进行了对比性数值模拟.计算所得速度、压力、温度及湍动能分布规律合理,从流动的角度分析表明该炉的生料进口、煤粉进口位置设计的合理性,对其深入研究具有参考意义.更多还原

【Abstract】 Based on the actual dimension of a big calciner,a three-dimensional turbulence flow of calciner was simulated by Realizable K-ε model and SIMPLE method under two different inlet conditions. The distribution rules of velocity,pressure,temperature and turbulent kinetic energy in the calciner were reasonable. As for flow,the results shew the good design of inlets of coal and cement raw meals of the calciner. It was useful reference to lucubrating the calciner.更多还原
