摘要

提出了一种计算有色冶金矿石电热回收过程传热传质的算法。为了实现该算法，采用了有限元法，考虑了反应器内部体积的复杂结构。采用有限元网格自动构建算法。提出了一种利用矩阵宽度优化和对称特性实现有限元方程的迭代算法。已经开发了一套程序，可以计算任何设计的电热矿石熔炼反应堆的运行模式，包括用于有色金属合金熔炼的那些。程序的界面是用户友好的。多文档界面以温度场和速度矢量等值线的形式将计算结果可视化。

Simulation and algorithmization of analysis of heat and mass transfer processes in chemical electrothermy units in non-ferrous metallurgy

Proposed is an algorithm for calculating heat and mass transfer in electrothermal ore recovery processes in non-ferrous metallurgy. To implement the algorithm, the finite element method was used, which allows to take into account complex configuration of the internal volume of the reactor. A finite element grid automatic construction algorithm was used. An iterative algorithm for the finite element equations implementation with the matrix width optimization and the use of symmetry properties is proposed. A set of programs that allows to calculate operating modes of electrothermal ore-smelting reactors of any design, including those used in the smelting of non-ferrous metal alloys, has been developed. The interface of the programs is user-friendly. The multi-document interface provides visualization of the calculation results in the form of isolines of temperature fields and velocity vectors.
