摘要
建立COREX熔化气化炉的半周三维冷态模型,利用高速摄影的方法跟踪冷态模型内示踪粒子的运动,得到冷模型观察面板处风口回旋区的颗粒运动信息,通过对大量颗粒运动信息的处理得到风口回旋区范围的颗粒速度标量场,运用分形理论对利用不同颗粒速度大小等值线界定的回旋区边界的"不规则"程度进行了研究,准确界定了风口回旋区边界.研究结果为风口回旋区的宏观动力学计算以及数值模拟提供准确的边界条件.
A three-dimensional semicircular cold model of COREX melter gasifier was established for physical simulation. The particle motion information in the raceway was obtained by using high-speed photography to track the particle motion. The particle velocity scalar field was obtained through processing the data of particle motion information. The irregular degree of raceway boundary determined by the ira-velocity contour was discussed. The boundary of raceway is thereby determined precisely. The results can provide precise boundary conditions for macro kinetic calculation of raceway and numerical simulation.
