摘要
依据传热原理,建立了物料颗粒在投入窑内加热时升温过程的简化数学模型,用有限差分隐式格式推导了节点方程,并用高斯-赛代尔迭代法进行了编程数值求解。在计算机上模拟研究了物料颗粒在窑内的加热升温过程,探讨了颗粒大小及性质对加热升温过程的影响。研究结果对认识物料在窑内加热升温特性有一定积极作用,也为下一步的深入研究打下了基础。
Based on the principles of heat transfer,a simplified mathematical model for understanding heating up process of granular materials in furnace was proposed. The nodal algebraic equations were derived by implicit scheme of finite difference method and solved numerically by using Guass-Sediel iteration. The heating up process of granular materials was simulated on computer. The effects of granular size and its thermo-physical properties have been studied. The results of the study are helpful for understandings and further studies of heating up process of granular materials in furnace.
